semen = good for vegetarians?

My girlfriend is a vegetarian. I've heard semen is rich in protein, something vegetarians are somewhat deficient in. Does this hold any water/should I use this as an excuse for my request that she swallow?

unless you're a giant fag with absoluetly no life at all like the asshat who started this faggotory thread. He should burn in a grease fire and just die infinetly.
