weird question

Is it weird that for some reason I can't find myself to want to ever seeing myself having sex with a new partner. Cause I'm my life I have a good amount of partners and I'm afraid to have sex with someone new. I have had so stds in the past. Now I haven't had sex in 6 months due to that and that I am single and that I had a skin problem down stairs that isn't that bad but contagious. I have been cured for that and I'm kinda starting a relationship but I'm afraid to even think about being sexually active with him. (Note: I am just 20) but I don't know is this just normal or what. I need help cause I have been sexually fustrated but afraid to have sex again.
