is this age gap wrong?Watch
As long as he isn't coercing, manipulating or forcing you into having a relationship with him in any other way, it's not wrong.
I've always been attracted to guys who are much older.
As a 16-17 year old I dated guys in their 30s, 40s, 50s and early 60s.
Have never dated a guy in his 20s and never will.
