I can’t seem to orgasm

Hey!

So after my boyfriend tried to get me off a few times, i got a vibrator- because I heard that that would help me orgasm.

Alas, I enjoy using it, and having sex with him, but nothing has managed to make me finish!

I’ve tried using the vibrator with and without porn, ive tried sex, and oral. But still nothing!!

Any more tips that you guys can think of?
