Is bad sex life an ok reason to split up

[Pineappleonthepizza]

Been together 2 years, and the sex is becoming less and less. Also its very vanilla, i have brought up how i feel and he says sex isnt important to him.
He wont do oral, use fingers and barely goes on top when we do do it. Its making me less attracted to him .
Other aspects are great, its just the sex isnt there for me

But that equally doesn't mean homosexuality. Maybe he likes his partner to be in charge or he has a lower back problem. No idea why people jump to 'he's gay!' as soon as there's a sexual compatibility issue.

Just out of interest, I assume you do all those things for him ?
oral, hands etc

Has sex with him ever been good? Just wondering why you’ve stayed for 2 years with a crap sex life?

That's not vanilla that's crap! It sounds like he's not interested in your enjoyment, which would be more of an issue than the sex itself, it's selfishness.
I had a boyfriend at uni and the sex wasn't great tbh (PE) but he was eager to please in other ways, that makes the difference to me.

As pp have said, you don't have to have any reason to split up with someone. You can leave them because you don't like their eyebrows or their Abba fixation if you want. There is no threshold you have to meet.

And sexual compatibility is important - so it seems very sensible to end things if you aren't compatible in that area.

It's of concern that you have asked other people's opinion on this - as though you doubt your own ability to make the decision.

You are entitled to be completely happy in your relationship. And if you aren't happy - for whatever reason - you have every right to walk away. The other person doesn't have to agree with you. Noone else needs to agree with you. So long as that's what you want - it's the right thing to do.
