Make me last shorter or he last longer?

I'm kinda frustrated. I enjoy having sex with my mate but he comes quickly, as I've been told most guys do. Or at least way quicker than me. Which means often times I won't get off at all. Even if we play around with myself afterward... Either the mood will pass or I just get tired of trying. It is deeply unsettling... You know, because orgasms are amazing.

I would prefer if we worked on me being faster, not him lasting longer or maybe a little of both. Because of my length, I actually get tired of trying to get there. Sometimes the idea it will take me awhile IF I ever do get off would be enough to not even want to try it and I think he low key feels the same. He also feels bad he can't get me off, but it is definitely not him. Masturbation is worse in that sense.

Any tips?
