My mate is breaking down

ok so these are a few questions from a mate of mine that im asking for him:

1st question:he says that when he masturbates he doesnt c*m. he orgasms but nothing comes out.why isnt he cuming?

2nd question:when he is having sex with his girlfriend he doesnt org**m very often. only bout once every 5 times they have sex. he loves her heaps. his girlfriend thinks that he doesnt luv her anymore but he does. they might be going to break up.

please help. my mate is breaking down ova these 2 things.

note:me an my mate aint gay. we are just close an thats why we can talk bout stuff like this.

well to awnser question #1...he could just not be developing sperm...it happens..so he should go get that checked out to make sure...and about the org**m thing...he just isn't enjoying it enough to have one I guess...

I'd say he should just go to the doctor and get it checked out.
