Young lady, first thing, break up what you have to say into paragraphs, it makes it easier to read. Also take out the irrelevant stuff so it's shorter.

"I know a guy, we talked and we told each other we're virgins, but I met a girl who claims to be his ex-girlfriend and she says he's had sex, a lot, now I see his pictures on Facebook and he's showing off a lot, and I'm not sure who's lying to me."

He might be lying or he might not be; a guy will say just about anything to get laid, and yes, they do lie. Or she could be lying to try to drive you away from him so she can now have (exclusive) access to him.

Clearly one of them is lying to you. Let's also not forget, guys who admit they are a virgin get teased a lot, so he may be lying to everyone else but not to you. All you can do is watch and wait. Now, consider, would it have mattered to you if he just liked you and wanted you (sexually) but admitted he wasn't a virgin? It is so common for people to lie - both ways, sometimes they claim they're a virgin or fewer lovers than they had, and sometimes they claim they've had sex before when they're still a virgin - because they're afraid the truth will scare the other person away. And sometimes people are shocked by the truth. It's so common that I don't even really see it as much of a lie.

If you like the guy and might want to have sex with him at some point in the future - especially if whether or not he's a virgin doesn't matter - then you could talk to him about it.

Presumably you're not so horny you really want to have sex right away, so what you can do is watch both of them. People who lie will repeat it. Perhaps you can contact him anonymously over social media like Facebook or Twitter using a new account, an alias so that he doesn't know it's you, pretend to be someone else and see if he admits he is, or isn't, a virgin. Or try to find out if she's likely to lie about things. But if you do this take the information to your grave, don't tell them you were spying on them, especially if you find out they were telling you the truth.

I have no idea what to tell you other than that you'll just have to watch what happens and see.

Good luck, you're gonna need it.
