when my girlfriend gives me a blowjob, she can never bring to the point of cumming. She feels furstated b/c she can't get me off. i would love for too but she can't. We have tried it 3 or 4 times but i feel nothing. any advice or tips for her

It is one of two things:

She is doing everything right and you are just too self-conscious. So not a thing she can do about that.

She is not doing it right and then you are the person who needs to tel her what she needs to do different to make it happen.

BUT, realize that there are giys who cannot get off this way. It might feel great, but a mouth can simply not do what a hand can do. So let her do it for awhile - then when you want to orgasm finish yourself off with your hand.

Have your G/F suck you until you cant wait any more. Then, instead of jerking off your-self, let your G/F do it. I had a G/F who wouldnt swallow, so as soon as she felt I was gonna come, she would finish me off by hand, this is what she did and It wasnt too bad.

Ease up man four times isnt enough to get used to drinking decaf compared to caffinated
my point is when a girl and a guy at the ages you and your lady are , expierience lets say "technical dificulties" its far to early in your relationship to know that its a problem and not something as simple as comunication , talk my friend and tell her what feels good and what doesnt ,
obviously something in her technique isnt doing the job for you and she is just working twice as hard for half as much.
tell her what you want and assure her she isnt making mistakes im in my 30's and i still find it hard to cum when my girlfriend of 5 years is giving me head then again there are times that i loose controle and find myself being a minute man the maral of this is we dont come with owner manuals and direction guides ,communicate you gotta communicate.
good luck my friend time will be the answer to your delima

thats all i got to say about that.......
