Is a new relationship possible without sex?

I think it's very possible, but only if both are happy with the "no sex" stance.

I'm a bit confused about what 'the other stuff' is.

I think you do need to reiterate your stance.

There's more to sex than penetration but if you are finding even kissing a turn off and say you feel no physical attraction then what you have is a re-found friendship and no more.

You could seek some medical advice about your lack of libido but for now you need to be frank with him about how you do or rather don't feel. If sex is important to him then you must give him a chance to walk away.

FWIW, I know a couple who got together under exactly these circumstances. He thought she would come around. She thought she might, but she never did. He has been seeking sex elsewhere ever since.

I know of women who would be perfectly happy if their partner sought sex elsewhere.

"he joked "can't you just go really slowly""

I am afraid he is not on the same page as you are.

He obviously is hoping for more than you're willing to give.
So, its up to both of you if that happens or not.

Thanks everyone your views are very helpful. I need to reiterate the message.
Sounds like he's got hope it'll change
I'm adamant it won't.
The 'other stuff ' is non penetrative sex ie oral, heavy petting...
Don't want any of it

You'll have to make it perfectly clear, because i reckon he thinks he can win you over.
Good luck, whatever happens.

I think it’s pretty certain he won’t stop trying to persuade you that you’ll like it if you go along with his desire. Whether he will push it to a point that distresses you is something only you can judge.

Men aren’t much good at accepting when a woman who adores them really doesn’t want any kind of sexual relationship, and surely you wouldn’t want him in your house with the nagging thought that his urge is to persuade you that you’ll actually do want to go further.

You need to firmly reiterate that you’re not just being coy, you enjoy his company but you have zero intention of pursuing any physical relationship. I wonder if he will take no for an answer.

I agree with MissAdventure you know you don’t want a sexual relationship with him, even kissing and he thinks he just has to take his time but that you’re going to give in eventually.
