I'm a older man and my wife will sometimes do oral sex with me she has told me i should taste my sperm. is it wrong to do so? should i try it?

No worries: Sharing a pizza, a scone, an ice cream cone, some saliva, semen, or vaginal fluids... it's no problem if both people want to. Semen comes from inside the body, so should be sterile unless a guy has an STD infection or prostate infection. Vaginal fluids have microorganisms that are harmless unless a woman has an STD infection or maybe intestinal parasites. Saliva, as we know, has lots of bacteria.
