I am in my mid 30s, and every since I can remember, i have wanted to eat my own load. I have successfully done it, maybe 10 times. I just cant do it, after I cum, I loose that urge.
Aparently im not alone. From what I read, lots of people are the same. I actually like the taste. I am not gay, I have no urge to taste someone elses cum, just mine.
I once had a girlfriend who told me she wanted me to suck it out of her pussy after we fucked. I did, and I absolutely loved every drop.
