Condoms are weird. Just the thought of putting on a condom makes a dick go flaccid sometimes when I think about how much it'll cut the feeling for me.
It depends though.
If I'm already accustomed to having raw sex with someone then i'm asked to start using condoms now, that's when it becomes kinda weird for me, but if i've been using a condom from the jump, then it's fine.
"Thin condoms" are a good compromise for this but they're notorious for breaking easily.
