Anybody with a sissy husband?

So my husband is a sissy aka I’m- white girl he’s a white guy and he fantasizes about the idea of me having sex with mostly big black dudes.

He has been cheated on before (not telling these girls this fantasy or telling them it’s ok to have sex with other guys outside of their relationship) he has only told me.

I am just wondering if any other women have this kind of husband and if their husband usually initiates the sex? My husband doesn’t initiate sex very often and it does bother me but sometimes I think it’s bc of this fantasy and due to him being smaller in size he might be insecure bc he has been cheated on a lot?
