Shower sex... condom?

So I’ve never had shower sex but my bf -who is way more experienced than me- wanted to try it but says it’s very... rough... friction wise.

I’m VERY adamant about using a condom every time we do anything -which is something he isn’t used to but is very willing to do to make it more enjoyable and less stressful for me

(Im also on the pill but I’m in a medical grad school I don’t have time for accidents or even the stress of worrying about it lol)

So I was just wondering if anyone has ever done shower sex with a condom on?

Does it help?

Does it stay on?

Just stick with sex elsewhere?
