What should i do!? PLEASE HELP!?

do NOT say you are over-reacting, because this is actually a really important topic. If you guys are truly close enough in your relationship, I would ask him if he could get tested, just in case. Explain to him that you still trust him any stuff, but for your sake and any possible child(rens) sake, anything he has will get passed onto you AND children.

If you are not a virgin, maybe you should get tested too, this would make it easier to convince him to get tested as well.

Not that I'm saying anything bad about his ex, but you never know who else she might have slept with or what she could have passed onto your boyfriend, or any kind of disease/infection that might have gotten passed down in someone's family-genes and stuff like that :)

Once you do have sex, there's no going back, so just make sure this is what you want to do.

I'd feel the same way as you. However I always talk to my boyfriend when I'm uncomfortable or unhappy with things. Like before we even knew each other he had put his hand in another girls pants. Just the thought makes me greatly unhappy. But he always just makes me feel better and says not to worry and stuff. So talk to him about it maybe? It may make you feel better about the situation. Or try not thinking about it. Im sure you guys love each other if you're deciding to have sex. That other girl doesn't mean nothing to him anymore. :)

Best of luck

I would just go for it, if he isn't still seeing her. Just get over it, and see where it goes from there. Have fun you two! ;)
