No O - ever

I'm almost 24, been sexually active for eight years, and I'm a single mom starting to date again.

I've never had an orgasm from penetration, and only a few (like seriously two or three) from clitoral stimulation from past relationships.

I was told once that I'd be able to have an orgasm once I had kids or when I was older but still nothing.

I enjoy sex, it's fun and it feels great, so I don't understand why I'm not getting there. I've been with a lot of men & a few women, different techniques and multifarious members, had emotional connections and one-night stands, hoping maybe variety would lead me to finding what it takes to figure it out. I think I might've gotten close with the guy I'm seeing now, I started tearing up and pushed him away so maybe I just fight it? I'm not big on penetrative masturbating but I've tried that too and nada - I do get off with external play.

Is this something I just need to accept isn't going to happen for me? Is it the same thing anyway or a much different orgasm? Any help appreciated, I feel like I'm missing out.
