Currently partnered and have been very curious about bringing in the aspect of cuckolding to my relationship. I am a top but have always been self conscious about my size and notably how long I dont last during a session. I have been trying to figure a way how to bring up the idea of opening our bedroom to a third. I would love to see my partner with a bull; who is hung larger than myself and the average size and can last longer in bed.

I'm trying to find ways to bring it up in a way that won't scare him off? Asking if other cucks in the group have any success with starting the conversation? Or if any bulls have any input how a couple have started or any feedback in general? I've also started to research options to last longer when topping (edging and numbing lube etc)

Also curious if there is any lingo I should know about cuckolding? or levels? I'm into comparing sizes esp with the bull but not really into cages.

Trying to find others with like minded situations and learn more.
