Are you all against organ donation and plasma donation and blood donations too? Cause then of course, youll be taking in someone elses DNA

But women, most of all. Remember that every man youve slept with, their DNA is still absorbed thru your vaginal walls. Most semen runs out, but some is absorbed. And then of course theres the BJ. Women will get a direct dose of anothers DNA from that.
They have found male DNA from partners in a womans brain matter. It was first assumed to be from a male fetus, but was disproven when not all the woman had a male son. Its from all her sex partners

This is why God always advised monogamy. If you had a pscyho boyfriend. part of him will always be with you..
