Advice from experienced sex lovers?

I am in high school and finally of legal age. I have obsessive compulsive disorder that can sometimes make it hard for me to come in physical contact with people. Despite this, I’ve recently been having one of my first “crushes” on a person at my school. He is almost certainly into me as well, but I find myself in the predicament where I get extremely anxious around him. I want to have sex with him, but i don’t know if I want a relationship or to be friends with benefits or what. I also find myself falling into a submissive role with him. I am afraid I won’t be able to do what I want to do because of my aversion to human touch. I also don’t know how much I want to bring BDSM into my life. Any advice from kinky people and/or ocd sufferers?
