don't get defensive dude, just buy some condoms.
And don't think you are out of the woods yet, women can have their period for months into a pregnancy and she could very well be pregnant now. If you have unprotected sex, or a condom break then call the local health department and ask for a morning after pill prescription. It is just one pill she can take 24-48 hours after unprotected sex, it floods her with hormones and makes a period start. It is about 95% effective and at $30 is a fuck of a lot cheaper than any of the alternatives.
You should also know that one in five people you meet has herpes, and many people with herpes do not know they even have it. Some people are born with it and it can be caught very easily from casual contact. If you have unprotected sex you will get it in no time. There is no cure.
If you guys think a condom feels unnatural, just wait till you feel what herpes is like.
Nothing get you laid faster than a cock full of sores. chicks dig it.
