I'm a male, 30 years old, and I had sex two days ago, and yesterday I noticed red bumps under my pubic hair. I'm hoping, guessing, it was caused by her being on top and the friction of her moving back and forth. No itching, just a little burring, like a razor burn/rash after shaving. Been with this person for 3 months, but this is the first time this has occurred. It looks like irritation of the hair follicles, and for something to show up in a matter of 24 hours makes want to think this is the problem. I've read several posts online, but not many suggest prolonged friction in that area being the problem. Any ideas?
