I've been hooking up with this guy who I really like. We've had sex before and he lasted a good 15 mins or so (and that was my first time). But when I gave him head, he came literally 5-10 seconds into it. He said that the last time he was given head, he went limp. Does this mean I was good at it, or what? I'm so confused. I mean I am glad I was able to pleasure him, but I kinda wanted something in return, ya know? and after he came, he wasn't in the mood for anything else.. Did I do something wrong or what?
Ok he was just heaps excited at the idea of getting head. Even though he says differently, I reckon it was the first blowjob he's ever had and he was just a little too turned on by the thought. He wanted you to think he was manly so he said he went "limp" last time just to show off.
Otherwise, after a guy cums, he generally doesn't want to do anymore sexual stuff for a while.
If you "want something in return", get it before you go down on him, or do 69.
You have to tease him first to show you want something, try not to give him anything until he is giving you something, and yes as soon as a guy cums he does lose his sex drive instantly, as for the 5-10 seconds thing, that might be an inconsistent issue he has, try it again and if it happens again maybe he needs to get that checked...
If it happens just once you really shouldn't think anything of it except that he was really excited. If it happens multiple times then you should find out if he'd be up for a round two. As long as he is, there's really no issue.
