I've [Male] never ruined many orgasms nor edged much. It's always been hard to get close but not too close. Online, people discuss ruining and edging a lot, and I've long gotten the sense it's easier for most people than it is me. Now I'm questioning that and interested in hearing others' experiences. For example, I don't get much ejaculate each time I try to ruin, and I'd quickly go too far if I tried edging. I don't know if this is related, but I've generally had low 'stamina' (for penile stimulation; ie, don't last long in bed, premature ejaculation) because outside of when being in a relationship trying to maintain stamina has seemed pointless.

Do you find ruining or edging easy? Has it required practice for you to be able to do what you do? Lots of practice? Do you think ruining/edging ability is related to 'sexual stamina' (like those who are good at one are probably good at the other too)?
