Does he even like it?

guys are often show not tell sort of characters. you'll read it easier in his body ever, than you ever would if he tried to tell you!

Try telling him your likes and dislikes, maybe that will open the door for him to tell you. Communication is key in any relationship, and it's very important to know your partner's view. Best of luck!

You don't actually need him to say it. you can see from the signs (does he get more and more active the longer you kissed, does his breathing becomes faster, etc) :)
