I've never been pegged, but I imagine it's very easy to damage your asshole being pegged. When I put my penis in a butt or a vagina, I can feel through my penis, I know to take it easy if you're super tight. If you're ramming a dildo into someone, you don't have that tactile sensation and I'm sure it's easy to go way too hard way too fast
Me and my current GF frequent hotels and will fuck each other in the ass and then she will finish by giving me a golden shower it’s fucking unreal 10/10 orgasm just drop hints and joke about it at first then just buy one and make it happen like previous posts it depends on the girl my gf is a skinny alt girl that gives 0 fucks and rails and degrades me but can almost instantly switch it up when I’m in her ass choking her out just gotta have no reservations and go all out good luck OP
