My doctor (way back when) was suprised I could touch my feet, so the flexibility aspect is there, but i've never worked out, or stretched for any length of time. I can do a half-back flip as you might call it and have my cock above my mouth, but it's pretty far from it - not too bad though.
So my question is:
should I even attempt to stretch to *try* SS? I don't want to take the risk of injuring my back.
Just to let everyone know, yoga is not an option here (the classes), they're far from my house and i'm tight on cash.
I believe it is possible for me to at least get "close" to my mouth, but not in tongue/lip range. I'm just wondering if there is a position that is not hard on the back. I want to go for the "x position" but with the pictures I saw, it looks like your spine is pretty damn curved to get that penis in

So.. should I just forget about it and keep to SF? or attempt it after stretching for a few weeks?
