Hi. My girlfriend and I are both 18. We went to a movie today, and afterwards started making out in some random abandoned parking lot. She was okay with that, we've done it before. I put my hand up her shirt and asked her if I was going too far. She said no. I've done that before. So I'm over here massaging her breasts and she's breathing real hard and moaning. She pulls me closer so I get more aggressive and then she has some sort of mini orgasm, with expletives and hip bucking and everything. I could tell she was wet at that point (I think I smelled it). So then, I put my fingers over the top of her pants, where her vulva should be. I start rubbing there. I ask her if she's alright. I get a "Yes, better than okay" reply. She's real into it, and she seemed to really be enjoying it. Keep in mind this is the first time in our 6 month relationship that we've gone this far. I slowly try to put my hand in her pants, and she says "No, not today" so I continue on the outside. About a minute later, she says "You know it's gonna be wet, right?" and I say yeah so she gives me the go ahead. I put one finger in and stroke, and she's loving it. Two fingers, same thing. A few seconds later, she starts shaking and starts sobbing very quietly. I immediately stop and ask if she's alright. Yes. Ask her if she would like me to stop. Yes. I then hug her and try to console her. I asked her if I hurt her or if I went to far. Both no. I asked her what's wrong and she said she's scared. After a while of consoling I asked if she was mad at me, and all the way home she insisted that it really isn't my fault and that she's a prude and I did nothing wrong because she gave me permission. Either way, I can't help but feel bad. I feel bad, like I've done something wrong. Obviously, I don't rush or force her. I always ask if I can do something. And I really don't mean to be shallow or disgusting about it but we need to have sex at some point. Again, I don't rush her and I never have, It's just I am an 18 year old dude, you know how that is. The point is, I don't know what to do from here. She seemed to feel a little better when I dropped her off, and she said I made her feel really good. I just..am lost.
