lack of orgasm

so my boyfriend and i started having sex back in june/july (we've been together since november 2014) but we've been doing sexual activities since last december/january but hes only made me cum once or twice in that period of time, meaning 99% of the time i'm faking it. its not that it doesn't feel good, its just that he can't do it like i can i guess? i don't know but i feel awful for faking it but it would take so long if i actually did cum... any advice??
