I think I might be dating an introvert

So I've know this guy for over a year. But things started happening between us just a months ago. We got sexual quite quickly. His friends call me his girl. But most of the time we watch movies in his room. Whenever I bring up going out he seems to get nervous. In the past I've come aggressive to men and I'm trying to tame that down cause I think I might scare him away. He says likes me alot and this is new to me. Should I just let it flow or let him go?
