tips for topping without a prosthetic?

I recently got a (cis) boyfriend for the first time and we’re both extremely new to everything. I’ve made clear I wouldn’t bottom because of my dysphoria and so far he seems to enjoy receiving, but he has basically no experience with what he likes or dislikes so it’s something we’re both learning.

I don’t have the means to get a prosthetic and it would probably be moving too quickly regardless of how much I would enjoy it, but I still want him to have a good time and don’t really know how to do that. So far he’s said he enjoyed what we’ve been doing but I don’t have the anatomy to know how things feel on his end, and his expectations are quite low because he has even less sexual experience than I do.

All this to ask, is there anything you guys have found most cis dudes like? any specific tips? I’d really appreciate any help
