From what you have stated I would the say the only way you are going to achieve your goal of becoming experience in sex with out a steady sexual partner is to have many one night stands, and that in imo is not safe.

OR - you could try finding one of those "friends with benefits" if you dare?

I personally think you may be placing to much pressure on your self to be the man of romance and love based solely on your age.... as I know a few males that waited to engage in sex until they were around twenty years old and the are doing fine.
