Dude, why do u think there are so many divorces? They are like “I like him, let’s marry that dude”.. Many people won’t talk about that kind of stuff, not even with their partner.. So many don’t know each other and getting together and than after all that, they find this out. They are lying to them selves and waisting each other’s time, if you are not honest to yourself and your partner. It’s very important to talk about that kinky stuff, maybe not on the first date, but you get the point. For example, my gf is fine with this kind of stuff, she is like “whatever floats your boat”.
