Oral sex, help

My boyfriend and I have been dating for over 7 months. I lost my virginity to him. I've never been like a very sexual person, meaning that I get wet if he does somethings, but I wouldn't mind if we didn't have sex. I just not feel horny. (For anyone, never)

A few times he has gone down on me, and the first time I was like "Hm. Yeah. Wet. I just feel sth wet" but I thought it was normal because it was the first time...

Nope

Just twice I have felt like an orgasm coming, but I never finish (this happens with penetration too, I've never orgasmed and believe me when I say I've had a lot of sex in very different positions).

And many times, he hits a spot I guess it's the urethra, and it burns.

So I always tell him to stop because yeah, wet and burns. So fucking fun.

We have tried taking it slowly, fast, clitoris sucking, massaging the clitoris (which is uncomfortable as fuck? Soft or harsh, I can't)

So yeah, we almost broke up twice because I'm unable to receive pleasure from sex and he ends up feeling bad for me because he only hurts me (penetration and fingering are also very unpleasant.

The first leaves me breathless when he hits a spot or burns, and the second one, when he hits what he says is the G point, I feel like I'm about to pee but if also hurts a bit (I've tried peeing before sex because I know this sensation is not rare), it's as annoying as having water up your nostrils. Not gonna die but you know, uncomfortable.

Some tips please?
