Hey folks, thanks for the replies!
Well, it seems I am not alone which makes me feel a bit reassured I'm not a freak (not that I needed it, but thanks). I might try to tug one off standing up to see if I can but it just seems such an odd feeling to do it. My body is saying...go on, sit on your ass, it's much easier! This is what happened during the gloryhole experience. My head started thinking...this would be so much easier if I was sat down at least! So maybe partially psychological, maybe if I achieve it once...the next will be easier?
As for a porn star...haha, yeah, I am not a 5 min wonder by any means and cum for bloody ages (which puts off some WGs with CIM!). Though it is often a curse. I am SO bloody jealous of you guys who get 2 pops in a 30 min session, I barely manage one!
The shower wank completely eludes me though, I need porn...and don't fancy ruining my phone.
