Orgasm

I love having sex with my SO but I can't even seem to orgasm. I've never had one. The sex feels so good and definitely has me moaning, but I just can't seem to get to that point. There have been times when I thought I was about to, but didn't. What's wrong with me? I just need to know if there are other girls out there that are the same so I don't feel like this is just a me thing.  😩😩 any advice is great please!
