orgasms

okay so I got a question. I‘m 19 and except a few make out scenes with strangers I never had anything sexual with anyone.

I‘m now in my first serious relationship and I‘m head over heels in love. He gave me all the time I needed to get into the sexual stuff and I was so scared I wouldn‘t like it or something but omg it‘s so much fun. We are about to have sex for the first time too and here‘s what I‘m scared of:

I haven‘t been able to have an orgasm yet.

Don‘t get me wrong it all feels incredibly good but I couldn‘t orgasm through oral sex or if he fingered me yet at all. And I really want to. I feel like a fuck up honestly and I‘m really sorry for him too cause he just wants me to feel good. The thing is I can‘t cum when I finger myself either. I get orgasms from dry humping which is incredibly embarrassing for me and I just want to be normal..? What can I do so him and I can enjoy eachother even more all I want is for me to get orgasms when I‘m with him I love him so much why am I like this😫
