Why doesnt my boyfriend cum?

when I am giving my boyfriend a handjob he doesnt cum.. why is that and how can I make him cum... should I grip it a little tighter cause he says that I can but I dont want to hurt him... please help ~Kaitlyn~

practice, be patient use your tongue and mouth and gently lick and suck like it's a frozen popsicle.

My boyfriend is the same.
Doesn't mean you aren't good at what you are doing.
Some guys only come during sex.

ask him wut he wants you have to commnicate

because he jerks off too much and maybe he ran outta C..UM :O lol

pull the skin around the head tight so it is more sensitive. it should make it more intense for him and make him blow it

tewww bad. maybe he is just not sexually interested in you
