Advice!!!

Here’s a little background on the situation: this guy and I have been hooking up but I honestly want to ask him if he actually enjoys it. I’m not really sexually experienced nor do I have the best body. Also I’m really self conscious about everything, like if down there smell good or normal or if it taste good. As you can see I’m a worrier also mixed with self doubt. But I want to improve my sexual experience and I need tips and tricks. But I honestly don’t know how to ask him or if I should ask him at all. Any advice will greatly be appreciated! Please help.
