I ended up with a carpet burn on the top of my foot!!! Not with you - but just saying there are so many dangers out there sexually!!! Ouch!!! Taking a while to heal!

Yet there are worse places than the top of your foot for a carpet burn.

So sorry to hear about your knee injury. I know them well , unfortunately. I blew mine out table dancing.  
Have you had your MRI  ?

Make a safe out of a cardboard box. It's a newer version of d!ck in a box, it's "safe sex!"

and sex was safe.

Get one if the lovely ladies in Vegas to kiss it ? The knee , the knee !

And I don't "amaze" easily!!  LOL

boxers or briefs, eh??    ,,or "wrap it and pack it"! ........or "think inside the box!"    ok, I'll stop now!

My handle came directly as a result of sex on the floor, lol.
