This is common knowledge to me as I ***** a semen milkshake every morning. It's good for what ails ya,
Not my cum of course I don't produce nearly enough, I get mine from a variety of different sources; the postmans, the old man upstairs, his live in lover plus a couple of well meaning strangers on the street all put forward a sample that goes towards my delicious, life preserving shake.
If that doesn't work I raid the sperm bank.
I'm 78 don't you know and I don't look a day over 20.
