I haven't had any kind of intimacy, never mind actual sex, for a long time. I mean a very long time 
The opportunity has arisen now and looks to be just around the corner but I actually can't remember how to do anything. Also, although I'm passable when fully dressed, I'm no spring chicken and my body reflects that. I'm so nervous, please can anyone give me some words of wisdom on how to relax, let go and enjoy?
