How do I end things, while remaining friends?

[Theodoreb]

I decided to give things a go with a long-standing friend, he has erectile dysfunction and I have bipolar suffering severe hyper sexuality. When we first went out we agreed that he would use toys and other ways to satisfy my urges. However since we've gone out he kisses me and hugs me then says this is enough for me I've tried talking about it but he's not getting the message. I don't want to be with him and even if he does start sorting me out I feel resentful like he's only doing it to stop me leaving which I don't want.

So how do I end things while keeping the friendship?

I don't know that you can to be honest.
No matter how nice you are about it, it's still a big bruise to his ego (and probably won't help his ED)

I think you need to be prepared to walk away from the friendship.

I wouldn't worry about keeping the friendship tbh, just worry about yourself and leave.
I tried really hard to stay friends with my ex of 17 years and it just didn't work, he was angry, moody and kept letting me down so I just had to let him go.
There is always time to consider friendship at a later date but he may need to be left alone for a while to get over being dumped.

I think I'm going to have to face losing the friendship as I cannot carry on like this. It would be different if he was willing to do oral or work with his hands and toys but he isn't willing to do anything other than cuddle and kiss.
