No, i do not have to have sex in a relationship. I'm so confused a bout all of the code crap. i wil admit sometimes i do think it will make someone love me. i have learned over time it doesn't. The fact of the matter I have done it at time without enjoyment, because i thought it would make her happy. it means nothing unless you love the person you are doing it w> which i just found out that out over the last 3 yrs
