Just recently I sucked my man's dick for the first time and now ever since he doesn't seem to want sex just head.. I've asked him about it and he says it's not true but he doesn't seem to be cumming when we have sex it's like half-half.. sometimes he will and sometimes he won't.

Do you think he isn't attracted to me or he has a lot on his mind and it's stopping him from cumming or that he's sick of sex? I just want to make him happy and pleasured but my mouth is definitely starting to get sore and I'm wondering what's changed.

Just looking for advice :)
