I'm married, but have been given oral by men recently. Just yesterday after receiving a blowjob I noticed a small bump at the base of my penis. It doesn't have any white puss and just appeared after the bj yesterday. I keep everything trimmed and it was a vigorous amount of handjob to finish as well as the heat here in Michigan. I don't have any pain urinating, but this pump has me freaked out. I've had sex with a man once (stupidly unprotected where I topped). It seems to have calmed down overnight, but its still there. What are your thoughts on what it could be?
