Let's start with the fact that there is nothing wrong with you, this is not about how good/crap you are 'in bed'. So stop thinking it is!!
Let's come back to this comment...
he doesn't want me on any contraceptive
Why does what HE wants you to do with your body, more important to YOU, than what YOU want to do with YOUR body?
YOU don't want more children (yet) YOU choose how YOU want to control YOUR body not getting pregnant!! Not him. YOU.
Get yourself in some reliable contraception immediately & if you don't want to tell him don't, keep up with condoms EVERY TIME.
Do not risk bringing another baby into this.
Mind you, if it was me, we wouldn't be needing contraception because he wouldn't be coming anywhere near me!!
My take is that - he doesn't want you on contraception, but doesn't want to use to use condoms either, he wants you to get pregnant & feel totally trapped.
He wants to use your body to fuck condom less & anally & whatever else he fancies.
This is purely about sex, his way, and not about having mutually enjoyable sex with you.
He's selfish and nasty. I'd highly recommend you give serious thought to leaving him because he doesn't care about YOU.
I'm sorry because that's hard to hear, much less believe I know x
