I am 25(M) and never even touched hand of opposite sex

Oh, yeah, I was in the same boat, raised conservative Christian, dating wasn't allowed until you were 18, and you were supposed to be dating to get married. I was something like 26-ish before I kissed someone for the first time. (...And ended up having sex with them a few hours later; unfortunately, I had such distorted views of relationships that I scared them off.) I'm mildly autistic, have pretty severe ADHD, and yet, I've been married this time for eight years. (The first one lasted eleven, but the last five or six were... pretty rough.)

Get some therapy. Work through some strategies for meeting people, and building relationships. The therapy that works is going to depend on you; different people respond better or worse to different treatments.
