>>117515One time I didn't have any tissues to clean up my semen so I swallowed it. It dosen't taste very good. I don't reccomend. Also I read that swallowing semen causes an immune response because your body thinks it's a foreign agent, so I don't think it's a good idea to swallow it. I already have an autoimmune disease so I don't want to risk getting another one. If I had girlfriend, I tell her to spit out my semen and not swallow it if she gave me oral sex since I don't want her getting sick.
Your balls are "Immune privileged" which means that parts of the immune system are disabled in your balls, this is because your immune system would attack your own semen if it wasn't. Your semen has different DNA so your body thinks it's a foreign pathogen.
