I (23m) can’t finish from sex as my penis gets too sensitive, how can I desensitize it? /u/kuyakusho Sex

I had a frenuloplasty a couple months ago and as a result I’ve been able to have sex properly for the first time ever. It feels great, the only issue is that after about 10 minutes my head gets extremely sensitive, it feels like how it would feel after you’ve already finished, but I haven’t. It gets to the point where I can’t carry on as it’s too sensitive and I have to stop. This has led to me somewhat avoiding sex with my girlfriend (which she understands but is understandably frustrated by) as it’s knocked my confidence a lot. I find the only way I can finish is when I masturbate with the foreskin up over my glans, I can’t even finish when my gf does this (though that’s probably also a result of my confidence issues that have arisen as a result). What can I do to stop my head getting so sensitive during sex? Is it just a case of using it more? I’d really like to be able to finish during sex!
