Recently I've been working on stepping out of my old ways and have started having mild success. For instance, at 24 I finally kissed a girl (albeit a random one at a club) and have become accustomed to playing it cool. That said, I'm not sure what to do in my current situation and am looking for some advice as to what other people would do. It is as follows:

I'm a 24 year old professional with a decent salary in the tech industry and I started messaging girls on /r/gonewild. After a lot of trial and error, I've become rather adept at cybersex and have have gotten multiple girls off (not at the same time. haha) when video chatting on Skype. One of these girls just so happened to be an 18 year old college freshman who goes to school at a local college. She is in a sorority and is rather experienced but we have a pretty good rapport with one another.

This girl and I have chatted a few times but she doesn't realize how inexperienced I am in real life. While I've been too busy to do anything before, I have some time to meet her this week (she wants to hook up). I'm pretty sure she would see this as casual sex and I'm not looking for a relationship with an 18 year old. Still, my virgin guy instinct is still to sleep with her since I have the chance (mainly to end my virginity). My main concern is that we have a large age gap and all of my friends would be appalled if they knew I hooked up with a college freshman.

Does it seem wrong to sleep with someone under these circumstances?

tl;dr I'm 24, I'm a virgin, I'm not sure how to handle a seemingly simple situation

EDIT: Thanks for the input, in the end she had a family issue come up that she had to go home immediately for the summer
