I need advice

When I was little I was sexually abused by my step sister for four years. I haven't been open about it until now, but now that I am talking to a therapist about I feel like I should start taking steps towards trying to move on from that part of my life. Now that I'm in college I think I would like to try and start dating. When I was in high school I got plenty of offers but in the end I never ended up taking them, never kissed, had a boyfriend, all of it. I worried about how guys might react to finding out or, even though my experience happened through a girl, that I might feel afraid or have flashbacks or something by having a sexual experience, regardless that it would be a guy.

I want to try to have a romantic relationship, be able to try and have what girls who haven't gone through this have. But I don't even know where to start or what I should be cautious of. I would really like some advice.
