Is it healthy to drink other man semen?

There's no real difference, and depends how you approach it. You'd gain more energy from consuming an other man's semen than say your own, just because of the energy you expend from getting it. But some people can be allergic to the proteins in semen so consuming others semen could increase the chance you find someone's your allergic to if you are, also you could put yourself at a greater risk of contracting STD's.
