I have an older fiancé than me and we are having sex problems.

I started hanging out with a man taller than me. i feel protected and it gives me financial security, but sex things are a little different. i always liked to choose strong men, i like big hard cocks, i feel up and down for hours. my boyfriend is a good lover, but to find the heat is necessary some foreplay. sometimes using disguises i walk up and start to touch his cock, i do different things with my hands and mouth, especially in the ass, i try to put my fingers in it to massage his prostate. sometimes also i like to use a sex toy, i bought it to play with it, or for me if i stay too hot when it comes out. thought it would be a good idea to look for a younger lover, but i'm afraid my boyfriend will realize or find out, i'd rather not take risks now
