It is doubtful that a woman could swallow enough to make much of a difference.
Depends on how much jizz she swallows. She'd have to be swallowing a few litres a day to put weight on from it LOL!
Not sure what you mean with too much since it's rarely a lot that comes out. But no, the only harm it can cause you is if he has a STD.
Much like Bull semen is used in energy drinks such a Red Bull or Monster, male semen contains high amounts of caffeine. Studies have proven that swallowing semen during oral sex can actually help the recipients stamina during sexual activities. This is why it is important for women to swallow every time.
Just like any other physical trait, everyone is different when it comes to the amount they produce. What you produce is normal for you.
Use your hand in addition to your lips. Keep the teeth away from the penis as much as possible. It is good though to let your teeth gently rub the penis a little bit to raise the excitement level. If you can continue till orgasm, try to swallow the semen. It is very satisfying for the man to know you enjoy swallowing his semen.
none, what would semen be doing in the brain.
the average man has around 3 tablespoons of semen he can ejaculate.
One bull usually ejaculates around 7 mL of semen.
Lets think about that, we are talking about comparing 1/4 ounce of liquid semen ( about 10 grams of protein) to an 8-12 ounce piece of beef ( 80 grams of protein) ..NO SEMEN doesn't come close to the beef! I was amused to find a forum that asked young guys how much semen is in each ejaculation, some thought it was 3-4 ounces.. that's a shot glass X 2! It is a very small amount, 1/2 ounce is a HUGE ejaculation.
Semen is not a valid source of vitamin intake.
Semen is free. It's all protein! Eat as much as you want.
