I’ve been dating a guy for months and still can’t orgasm. Should I tell him?

I’m a 25-year-old woman and I’ve been dating a guy for a few months now.
The chemistry between us is amazing, I genuinely enjoy having sex with him, and the oral sex is great too. I find him very attractive and I feel comfortable with him.
The issue is that I still haven’t been able to orgasm with him. I enjoy everything we’re doing, but it just doesn’t happen.
He seems to think everything is going well, and I haven’t brought it up because I don’t want him to feel like he’s doing something wrong.
At this point I’m wondering if I should talk to him about it or just give it more time.
Has anyone else been in a similar situation? How did you handle it?
