<s>[INST] Hi, so im coming to you because I really need some thoughts and opinions from you about my sexual reactions. It seems that everytime I ejaculate almost immediately after I start to get this feel and uneasy and I notice my body temperature rise, even through the next couple of day I notice sweat stains under my arm pit that I would not get if I have not ejaculated. These feelings typically last around 7-10 days, after that period I feel pretty normal. This is a problem that keeps me away from sexual activity since I want to avoid this occurrence. So what are your thoughts on this matter because I get the biggest feeling that this is not normal and something is wrong. Also to add, I have been diagnosed with Hepatitis B but it is not chronic or activity currently. Im a really fir individual who exercise on a regular basis and play University level soccer. It would be much appreciated if you reply and give me your thoughts on the problem may be. As you can imagine it is something i shy away from and its hard for me to talk about. Thanks. [/INST] Thanks for asking in Chat Doctor forum In short: Experiencing hot flushes and sweating after sex/ejaculation is completely normal phenomenon. As you are very active in sports I think your Basal metabolic rate might be more and might be experiencing feeling of rise in temperature for many days.  I do not think your ejaculation and this problem is related. Please do visit a doctor and ask him to investigate you for hyperthyroidism /hypermetabolic states. Good luck </s>
