Need to quit getting myself off

I guess you could say I'm addicted to masturbation, I've been doing it nearly every day for 4 years. Don't get me wrong, daily orgasms aren't something to complain about but it has always affected my capability to orgasm from another person so I'd like to cut the habit, I want to enjoy sex with my boyfriend. Everytime I try, I fail within 3 days. tips?????
