Help with not going over the edge!

I’ve been into edging for a while though I’ve never really got to into it despite wanting too, until recently. For a while starting with my last relationship I got into the idea of edging for at most up to two hours before orgasming. Recently though I’ve been wanting to get into longer edges lasting from up to 3 days to maybe even months! However, I have a problem doing this as I get closer to orgasming I can control it for a while but eventually I ether just ruin or orgasm normally. I want to go longer but idk what to do to get a better control of my orgasms. Any advice would be nice! female orgasm denial Get your own Orgasm Control toys: For men: http://www.amzn.to/1V6XQvv For women: https://ift.tt/1UWn54n
