Can’t orgasm

Hello! I’m 23f and I’ve been with my partner for almost 3 years. Our intimate life is great I’d say however I’ve never had an orgasm from penetration alone. What we would do is either I finger myself during or he’ll eat me out after and honestly it always worked, just took time. However… I haven’t had one in months. We have been busy and sometimes we only get to fuck but there’s even been times when I finger myself or he eats me out but I just don’t get them? I haven’t masturbated either, I just don’t feel like it. The sex is good, I’m turned on, the head is good, I just can’t finish. I haven’t been well mentally and I haven’t even felt the desire to masturbate on my own either. I didn’t want to tell him cuz what if he felt bad so yesterday I had to fake it 🥲 I hate it but he was down there for like 20min and it was amazing but I just didn’t orgasm and I didn’t want him to think I didn’t like it.

Advice? What’s wrong with meeee
