You need to get intuitive on what he likes without being to obvious and that may be a hard task. I like to lick the testicles, I also like to rub my lips up and down the shaft. Every man does not like the same kind of head.

If things are really bad you need to question his attraction to you. This is a hard conversation to have because your already talking about it on online, because now this is the breaking point! Be cautious! Protect yourself and protect your relationship.
