I don't think you have to make it into a deal where "If you want anal you have to let me bend you over first" or make it (or everything) into domination or S&M or whatever...
Strapon sex is great. If done right! And if your comfortable doing it. Having it become a mess can ruin it so you have to take some action before hand to insure there is none.
Try it a few times then if you don't like it? I will be surprised. The Male Prostate is like the "G" spot for women...
