I'm not exactly clear on what you're asking, but from what I can gather you're worried about the appearance and wetness of your genitals after you had sex? If you're wondering if the things you've noticed are normal, I'd say that they likely are- no one person is alike, so everyone's body reacts differently to things like that. Wetness is definitely normal, whether you've had intercourse or not- most (if not all) women experience that from time to time. It may just be your body's reaction to something new (ie. first time intercourse).
As for the wrinkled appearance of your vulva, that's quite normal too. They all look different hun, it's nothing to be worried about. Though, I'm not so sure whether sexual intercourse could cause it to take on a wrinklier appearance- I've never heard of that happening, but if any of the other advos have an idea, I'd love to hear it. Wrinkliness (sp?) in that area is normal, and chances are that was the way it looked before, you just may not have noticed it previously.
And the hymen situation? Yes, going only a couple inches into your vagina can stretch or tear your hymen. But the thing is, your hymen may have already been completely or partially gone before you even had intercourse. Tampon use, masturbation, exercise and sports (ie. horseback riding, gymnastics, soccer, whatever), and all kinds of other things can erode your hymen. It's actually quite common. In fact, not all women are even born with a hymen at all, or only have a partial one.
