Orgasms - HELP ME

I can't orgasm AT ALL through penetration.....like not even to the point of getting close. I feel bad because he tries and tries and not even he can finish. It's horrible😭. Can anyone give me suggestions? I haven't been sexually active very long....I think we've done it about 4 times. Idk if maybe it's a side effect from the bc I take or maybe because I haven't been active long....we have tried different positions and NOTHING! SOMEONE HELP.
