Today I noticed several pimple like bumps above my penis under my pubic hair and one up higher towards my belly button, all somewhat white/skin colored. I popped the one by my belly button first and pus yellowish push came out just like a pimple, and not clear pus like it is with herpes. I tried popping another one later, and nothing but a little blood came out so I left it alone. None of them are red or sensitive in any way. I only noticed them when I happened to see the one by my belly button while I was peeing. I have no discharge, discoloration or any other issues of any kind. My girlfriend and I have sex about 4-5 times a week, sometimes unprotected. About 8 months ago she had a test come back indicating chlamydia, which she believes is wrong because her previous tests which she takes every 6 months for birth control have always been negative and I was the only person she'd been with during the previous 2. Just to be sure, I got a full std screening and came back negative. Some random information but hopefully helpful. I can't find anything online like what I have so hopefully one of you can help me!
