could possible be an irritation to latex if you don't use them often...I have had an almost similar situation that I am trying to figure out if it's herpes or was it a reaction to latex materials.
Worst case, if you're still worries, get an HSV-2 test (blood) test.
probably they are not herpes.
i agree i need to get checked for all these things and I plan to but for my peace of mind until then does this sound like herpes? (the red mark on the head of my penis has since faded almost completely) It's been a day now and the two red bumps have not increased in size or multiplied and there is still no itching, burning etc.
the best thing to do is to be seen and get these properly looked at.
because you had unprotected sex, you can follow up with proper testing at the proper times - chlamydia and gonorrhea after 1 week post encounter. syphilis anytime after 6 weeks. herpes, hiv and hepatitis after 3 months.
female condoms are more expensive but they don't rely on maintaining an erection for use. something worth looking into if staying erect while using a condom continues to be an issue.
