<human>: When I say I don't know what I'm doing I mean I don't know how to be in a relationship. Last year, I had a thing with a girl where she just led me on and I fell in love and eventually got trust issues and like no confidence. 

Anyways, fast forward to now, I'm in college and I met this girl a couple months ago on tinder. We talked a little but it kind of stopped and I assumed I'd never talk to her again. Out of the blue about 2 weeks ago she shoots me a text asking to hang out so we did and it was awesome, we spent the whole week together and last Friday we tried to have sex. It was my first time and she is really experienced so I didn't tell her that. Due to me being nervous and the fact that shes really hot I couldn't get it up. Two days later, almost the same thing but we fucked for like 30 seconds and I went soft. 

She said she likes me a lot but I feel like the lack of sex is making her lose interest. On top of it, I don't initiate anything because I just don't know what to do. I overthink everything and I end up just laying there. I just don't really know what to do and now she is going back home for 2 weeks and I'm scared she'll get back with her ex or something who she frequently hangs out with still.

Give me the gist of the text in a nutshell
<bot>: New girlfriend doesn't know she took my v card and now I'm concerned that she's losing interest due to lack of sex.
