Not sure what you are asking here...
Sex is not a deal- is it? If this like is a one night stand or something, then fine, go for it or not. You do what you like, it's your body. Sex is intimate- communication is the key and knowing your partner is what makes it a positive experience or possibly negative.
It sounds like you need to get to know them better, it takes time to for both partners to learn what the other likes, and maybe even longer to give into their fetishes!
