My boyfriend is bi

My boyfriend is bi and has told me he has fantasies about giving blow jobs and being a bottom. This does not bother me in any way, however, we have mutually agreed that we are seeing each other exclusively, so if he were to hook up with a man, he would be cheeting on me. I am a female and I am looking for tips on how to help him fulfill his sexual fantasies. I am usually the dom in our relationship and we have considered pegging before, but I'm looking for more options/ creative ways. Please comment with tips. (we have not actually had sex yet. Mutually saving ourselves for our marriage night to make it special, but we do hand and oral a lot)
