<s>[INST] I am 18 years old, I find a gloopy/lumpy discharge when I ejaculate. I m pretty sure I don t have an STI , as i have safe sex , and this has been a problem before I had any sexual activity. Reading other article it was suggested that this could be diet related or even due to diabetes , I don t have diabetes and restricted my diet to low sugar, and this had no effect. It is an inconsistent amount, and somedays there will be none at all. Infact I often find the day after a sexual encounter I no longer have the discharge, but then later returns as time passes. [/INST] Degree understand your concerns went through your details. I suggest you not to worry much. You are just 18, and you are being more exaggerating. The lumpy semen is a sign of health. It comes so because of your masturbation habits. Those lumps are clusters of sperm cells, ready to more forward inside the vagina and inseminate female eggs. Don't worry about your sexual health. The amount and viscosity of semen depends on so many things like, stress level, water intake, time of sex or masturbation etc. Do not worry about that too. You are a teen ager. Don't succumb to anxiety and think too much about sex or sexual matters. Concentrate on studies and career. For sexology solutions Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition. Hope this answers your query. Available for further clarifications. Good luck. </s>
