Shouldn't have to tell a good lover will ask, what do you like. Ones response to certain stimuli is self explanatory. Let's not make this harder than it is people communicate, communicate , communicate .
I agree, but I don't put it on the other person to ask me. I personally ask what my partner wants, and it's a really good way to be forward but not seem self absorbed. If you get them talking about their likes it is allot easier to work in yours. Often you will find allot of common interests, and at least you can come to understand where a compromise may be if your tastes diverge.
