Orgasm

I'm currently in a relationship, and it's my first serious relationship, so I've been going further than just kissing (not sex just yet) but my boyfriend is very open about pleasure and doesn't force it, but he encourages it and encourages me to pleasure myself, which I have tried multiple times, and I just can't get myself to orgasm (not with him either) and I'm starting to worry! I get turned on up to a certain point, but that's it. is there something wrong with me?
