So, you're the only human being on planet earth that can just "tell" if a woman's been exposed to HIV, herpes, syphlis, chlamydia, gonorrhea or HPV? Must be really cool to be you. Personally I'm gonna belly laugh when you come back here crying because your dick's in danger of falling off.
...And if you were so sure that it was alright to be doing what you're doing, you wouldn't be on here asking about it. Unless of course, you didn't really come here to get opinions, but to get your opinion validated.
Have you told the one that you "want to have a future with" that you're banging other women without a condom? Have you told her you're banging other women at all?
