I have a fiance older than me and we are having problems with sex.

I started going out with a man taller than me. I feel protected and it gives me financial security, but sexual things are a little bit different. I always liked to choose strong men, I like big and hard dicks, I keep feeling up and down for hours. my boyfriend is a good lover, but to find the heat you need some foreplay. Sometimes using disguises I walk and start touching his dick, I do different things with my hands and mouth, especially in the ass, I try to put my fingers on him to massage his prostate. Sometimes I also like to use a sex toy, I bought it to play with, or for me if it gets too hot when going out. I thought it would be a good idea to look for a younger lover, but I'm afraid my boyfriend will notice or find out, I prefer not to take any risks now
