I'm 19 and haven't had anything close to a sexual encounter in over a year, and I recently matched with this girl on tinder. We hit it off pretty well, and exchanged snaps. She's down to chill with me, but I feel like I've come across as needy and will fuck up hardcore if I invite her over. Plus I don't really know how to be sexual with someone I barely know. Any advice on how to overcome this?
