Why are most males unaware of the dangers associated with ejaculation whilst sitting upright with back straight on the edge of the sofa?

A Better question would be, why does this question have to be asked 15 times?

you again?


i thought your mother threw you out, didn't get that job did you?

There is no danger to be aware of.
Plenty of males have masturbated or had sex "whilst sitting upright with back straight on the edge of the sofa".
As you continue to post this rubbish without any evidence to support your claim, it only demonstrates that you have some unhealthy fixation with masturbation and sofas.
Present your evidence and vindicate yourself. I have only ask you to do this umpteen times, yet you NEVER do.
Spoilers... it's because you haven't any evidence.

On this site we have you and the sofa, Melanie/Kylie who gets her hair caught in her handcuffs and him with the rubber glove fetish.

I suggest you invite them around to your house where you can all wear rubber gloves and handcuffs and sit on your sofa, and talk about your perverted posts and dam well get off here.
Its boring for the rest of us. Year after year after year.

Prolargent 5x5 Extreme did exactly what I needed it for and will definitely recommend it to friends.

Why would anyone need to be aware of a non danger?

You are the only person who believes there is a danger.

Need to take a class on physiology and you would know your theory is incorrect.

Not again

thats a good myth

So unlikely in the grand scheme of things as this is a pretty unlikely position to be in.

There is no danger. What you described only happens to an extremely tiny portion of people.
