text: Let's see now. Male secretions, a.k.a. semen is made up of about 2–5% spermatozoa and some 60% of the volume is seminal plasma. Seminal plasma of humans contains a complex range of organic and inorganic constituents including metal and salt ions, sugars, lipids, steroid hormones, enzymes, prostaglandin hormones, amino acids and basic amines such as putrescine, spermine, spermidine and cadaverine. Since the seminal plasma provides a nutritive and protective medium for the spermatozoa during their journey through the female reproductive tract, it has been believed for a long time that the same protective properties can help protect skin from the environment.  The poster jnunz5353 suggests that there is a lot of acid in sperm, the truth is that there area lot of alkalis is sperm. The female reproductive tract if filled with acids, and the alkaline bases in the seminal plasma counteract the acids and protect DNA inside the sperm from acidic denaturation. \n\nAs for it's benefit to skin, Well, semen contains proteins, which tightens the skin helping with wrinkles. It also contains an abundance of natural lipids, essential amino acids and prostaglandin, natural substances which aid in skin repair and increase blood flow bringing in more nutrients to the to the skin. So I would venture to say that it's not bad and may be good. \n\nAs for female fluids, I would venture to say that they probably have little if nay skin health benefits since the vaginal microflora produce lactic acid and acid is not a good thing to ad to the skin unless you are trying to dry it out.
