Generally speaking, I respect a bottoms request of wearing a rubber if he mentions it up front. However, if we hookup 2nd meet, I will immediately start working to get in him bare. Most often, guys want it raw thanks to the overabundance of bb porn. I also think most guys are keen to the idea that guys who meet up to fuck multiple times are more honest vs 1 night stands.
On the flip side, I sometimes ask guys to rubber up only bc I enjoy the friction of the rubber and REALLY ENJOY when the rubber snaps. Only 1 dude pulled out and admitted what happened. Everyone else acts like all is good. Total mind fuck for them.
