no I like head, I just like sex even more, it depends on the situation if its a random girl that you just hooked up with you might not be able to do it and insiting on it could loose you sex in the future if its your gf or booty call then that's a different story, I would just explain to them how much you enjoy it and ask them why they don't like it, maybe they are worried that their skills aren't good or something like that, once you find out then you have to address the Concern
