What's in sperm? Will swallowing make my girlfriend gain weight?
 

There are many ingredients composing semen, and its makeup is the same from man to man. Here are a few of the constituent elements: vitamin C, calcium, chlorine, cholesterol, citric acid, creatine, fructose, lactic acid, magnesium, nitrogen, phosphorus, potassium, sodium, vitamin B12, and zinc.

So what effect will all this have on her waistline? Well, not much of an effect at all. The caloric content of the average ejaculate is estimated to be approximately 5 to 25 calories -- hardly the most fattening meal.

And for those of you who wrote in asking if semen is a good source of protein, its protein content is roughly equivalent to that found in the egg white of a large egg. So you're probably best off sticking with the eggs.

so you suggest i tell my gf she needs to stick to eggs ? lol you wish

Chin omlettes for everyone :)

she will get fat like a pig

If she gain weight it's cauz she's sucking the neighborhood
