Does saliva damage sperm?
well considering you ejaculate INSIDE the woman to get her pregnant most of the time, at least considering you are ttc i would imagine you are in fact ejaculating inside of her… and your tongue if it goes inside her at all does not go as far up as your penis does…. so regardless of oral sex and how much damage your saliva may or may not do to the sperm, it wont matter, the sperm are out of reach of your saliva…. but yes, to answer your question, saliva is harmful to sperm, but in your case, you have nothing to worry about…
