Like many fantasies, some work out for us, some don't and some are best left as just that, fantasies. Many men like sleeping with sissy's and enjoy it, luckily for me. Most sissy's me included are sexually obsessed anyway and we often see sex with men as a way of demonstrating our femininity. Most sissy's are especially orally obsessed.
I have slept with other sissy's and it's been ok for me and hopefully it's been good for the sissy's I've slept with. But I'd much rather sleep with a man any day. I'm sure there are many sissy's out there that would enjoy pleasuring you, so give it a go. What's the worst that could happen, you might enjoy! One thing is for certain, you'll get a free blowjob
