Question.me and my boyfriend has had intercourse 3 times and every time there's a numb feeling. i was wondering if it was because we took antibiotics?

Sensation & Sex: Antibiotic use would have no effect on sexual sensation. Frequent intercourse, either multiple times in one sexual encounter or done once over successive days, can cause some irritation and diminished sexual pleasure in the "over stimulated" genitalia. A rest period, proper hygiene and adequate recovery from any mild injury would be the best route to follow.
