Orgasm

Okay guys so I'm 21, I've only been with four men sexually ... I have never had a man give me an orgasm , I've only been able to do it to myself . BUT I realllly want to with my boyfriend , its not like he doesn't turn me on bc he really does, I just would like some tips to get things going ... I have tried so hard in bed to get off. Its becoming frustrating. He usually gets off rather quick . And a lot of the time just as he's getting off I'm about too as well but as soon as he stops , well you know ... Frustrating lol .
