user10950: Is it possible that Buddhist practice could cause a lack of interest or even repulsion of sex?  Lately I have tried to have sex a few times and I felt uninterested and repulsed by it. I was so repulsed that I couldn't even function down there. It feels so pointless to go through this entire ritual which takes so much energy and time for this tiny moment of pleasure which feels like a sneeze. It all seems so disgusting, the smells, the fluids etc. It's all rather filthy and I feel like my entire aura is dirty after.  I still have the desirous thoughts that lead me to seek it out but when I do it just doesn't happen. Is this a symptom of meditation practice? 

user10100: Yes, because sex is  five strands of sensuality, that the buddha called that it is the first of 3 very big suffering, mahādukkhandha, in mahādukkhakkhandhaSutta.
The lack of interest in five strands of sensuality, is require, before the practitioner will begin both of concentration meditation and insight meditation.

user5000: Have you, during Buddhist/medidation practice, contemplated sex and realized that you're repulsed by it, disgusted by it, aura dirty when doing it? Or has Buddhist/medidation practice lead you to contemplation of sex and realization that you're repulsed by it, disgusted by it, aura dirty when doing it?
If yes, then your repulsion is a symptom of Buddhist/meditation practice.
If no, then your repulsion can be a symptom of something else. This doesn't mean that it can't be from Buddhist/meditation practice. It still can be from Buddhist/meditation practice, but it can also be a symptom of something else, completely unrelated to Buddhist/meditation practice.

user12267: It sounds like it's a symptom of meditation practice, but at the same time it sounds like an intermediate stage on the path to full understanding. You have understood that sense-pleasures are a distraction from what's real and that even the notion that they're "good" and should be sought is just an optional thought in your head, not a law of nature, but this has led you to develop an aversion to the sense perceptions that come with intimate contact and now you're attached to that aversion and the concept that these perceptions feel "bad". You have only replaced the attachment to pleasure with an attachment to displeasure. :)
Try to continue down the path and see all physical sensations as just physical sensations, not "good", not "bad", not compelling you to always reflexively or compulsively seek them, not compelling you to always run away from them, just physical things that are happening in an interaction of human bodies.
On the other hand, go deeper into what makes you want a relationship in the first place. Is it to get some sense-pleasures from some physical interactions or is it to love and be loved? If you discover you have some deeper motive than simple physical pleasure then you should be able to use that motive to color all your physical interactions with that person, and get to where you see all sense-perceptions that you create together as manifestations of what, fundamentally, has brought and keeps the two of you together. (This should also help in getting you past the roadblock you were talking about that is everyone's expectation that you "put out" right from the start - if you're clear on why, deeply, fundamentally, you want to be with that person, and keep that deeper reason at the forefront of your mind through all interactions, all physical sensations you get with them - even during "too early" intercourse - should become as acceptable or "positive" as that original motive itself.)
[Note: "not good, not bad" is a non-dualist teaching, specific to Mahayana, Zen, Advaita Vedanta, Daoism and the like. Adepts of Theravadist traditions may disagree with this framing.]

user-1: I would argue that, logically, some meditators -- who are not necessarily affiliated with Buddhism -- still have sex and do not live a celibate life. Therefore, meditation in itself is unlikely to cause disgust as you describe. 
However, some things must be kept in mind. There are different types of meditation, leading to different results. Contemplating the impurities of the body, for example, might cause what you describe. 
Within Buddhism, sexuality isn't immoral, but rather leads to subsequent suffering. This is because of the nature of attachment, especially such gross types of attachment as sexual desire. The Dalai Lama has claimed sexuality is always a source of suffering.
Since you speak of auras, I suspect you are into spirituality which may not necessarily subscribe to Buddhism. Buddhism itself allows sexuality, as long as it isn't sexual misconduct. I imagine your feelings of disgust arise from conditions distinct from meditation, and if this is the case, then the answer requires considerations beyond what is currently available to me. 
Hope you'll figure out this situation,
Eggman. 

user8157: Meditation can make the mind more sensitive to coarse/unrefined things however becoming accustomed to refined experiences of love or intimacy can also result in loveless sex feeling pointless & coarse. 
Buddhism (example, the Piyavagga) refers to different levels or degrees of love, which accord with the natural purpose of love, which is to evolve from craving, to lust, to attachment, to affection, to endearment and finally to self-sacrifice (caga) & metta-karuna (friendship & compassion).
For example, the self-seeking lust of a teenager is different to the self-sacrificing love of a mother, as described in the Metta Sutta, as follows:

Even as a mother protects with her life  Her child, her only child, so with a boundless heart
      Should one cherish all living beings...

In your previous question, you referred to a 17 year "intimate" relationship, which came to an end. Often, random sexual acts feel pointless after intimate love is known because sex itself is something the developed human grows/evolves out of, in favour of intimacy & friendship. 
It is like becoming accustomed to eating good food. If one is forced to eat bad  food, the bad food is not enjoyable. Similarly, random sex after the ending of an intimate relationship can be unenjoyable because life evolves forwards or upwards rather than falls backwards, which is described in MN 75: 

Suppose, Māgandiya, a householder or a householder’s son was rich, with great wealth and property, and being provided and endowed with
  the five cords of sensual pleasure, he might enjoy himself with forms
  cognizable by the eye…with sounds cognizable by the ear…with odours
  cognizable by the nose…with flavours cognizable by the tongue…with
  tangibles cognizable by the body that are wished for, desired,
  agreeable, and likeable, connected with sensual desire and provocative
  of lust. Having conducted himself well in body, speech, and mind, on
  the dissolution of the body, after death, he might reappear in a happy
  destination, in the heavenly world in the retinue of the gods of the
  Thirty-three; and there, surrounded by a group of nymphs in the
  Nandana Grove, he would enjoy himself, provided and endowed with the
  five cords of divine sensual pleasure. Suppose he saw a householder or
  a householder’s son enjoying himself, provided and endowed with the
  five cords of human sensual pleasure. What do you think, Māgandiya?
  Would that young god surrounded by the group of nymphs in the Nandana
  Grove, enjoying himself, provided and endowed with the five cords of
  divine sensual pleasure, envy the householder or the householder’s son
  for the five cords of human sensual pleasure or would he be enticed by
  human sensual pleasures?”
“No, Master Gotama. Why not? Because divine sensual pleasures are more excellent and sublime than human sensual pleasures.”
