Sex styles ?

Not sure if anyone else will relate but… So, I lost my virginity to my ex boyfriend right. We were together a couple months and we’re always having sex. Now I want to have sex with someone else but I’m nervous . Because me and my ex literally had our specific things and positions and all that stuff that we always used to do. I’m just nervous because when I get with this other guy he won’t do all that stuff I’m used to . What if I don’t know what to do . I might just be paranoid but, I’m scared I will feel new at it again?
