Well, I wish I could help, but I have to say that anything I've fantasized about and followed up on in real life, I've enjoyed. This has included facials, anal sex, etc. I will say that I have willingly complied with a partner's fantasies, and they have said it wasn't all they thought it would be - thankfully through no fault of mine. One g/f really wanted me to perform anal with her and then put my cock right in her mouth. She really liked licking my ass (though I didn't particularly enjoy this) and she said she wanted to taste hers. I thought this was a little unhygeinic to say the least, and something only reserved for freaky hardcore porn. But we did it, and once I was in her mouth, she pulled away and started spitting! Then she yelled "gross!" I thought that was odd, because why should my ass (which she enjoyed) taste any different than hers? Admittedly I never went down there on her, just because I thought it was gross to begin with - despite her "anal" (pun intended) tendencies toward ultra-cleanliness. (she was one of those hand washers that grabs the bathroom door handle with hand towels on the way out, etc.). But anyway, she liked licking, she wanted to taste herself, and it didn't work out. So I can relate somewhat...
