Looking for the real experience

I’ve been a relationship for two years now and my partner is an awesome guy but when it comes to sex he’s always very vanilla and tho I can enjoy it I know I’m the complete opposite. I’ve been wanting to have a real superior male to use me, humiliate me, degrade me, use toys, invite others to use me, etc and have a lot of fantasies that I know only a real dom top could do…not even sure if this is the right place to post it, but would someone be interested or tell me what app or website I could actually use to find someone like that? Probably a lot of people would think I shouldn’t as I’m in a relationship but that part of my sexual life makes me feel frustrated sometimes and I would be so happy to find someone to be his sex slave behind scenes…thank yall!!
