I tend to be a one woman kind of guy, but I don’t see anything slutty and certainly nothing deviant about your approach to your sexuality. Once we get beyond sex for procreation, then to me it’s mostly about creating pleasure and what works for you is what works for you. Too many people get way too caught up in the assumption that their definition of how it’s supposed to work is the only definition. I call humbug on that! You do you. Cheers.
