I had unprotected sex with a woman , it wasn t for long because I was drunk and passed out . I woke up with a rash . The bedroom wasn t the cleanest and wondering if it is from sex or maybe bedbugs . It is only under my belly button . The get real itchy .
Hi, Most likely it's from either bed bugs or insect bites. I suggest you to use a moderately potent topical steroid cream e.g. either Mometasone Furnace or Triamcinolone Acetone, twice daily for a week.  In addition, I suggest you to take an oral antihistamine e.g. tab Cetirizine once a day for symptomatic relief from itching. Hope I have answered your query. Let me know if I can assist you further.
