Why can I only orgasm when I’m alone!?

Emily

For some reason I can never orgasm when I’m with my girlfriend

We’ve been together 8 months now and we’re both each other’s first times

When I’m masturbating I can orgasm no problem but when I’m with her I have to help it along and most times I never come

I LOVE when we have sex and it feels so amazing but I’m always just not quite there when it comes to orgasms

Any tips?
