Mine, when we used to have sex more than once in a blue moon, was dull, predictable and repetitive.
I could wright the script of exactly who would do what, to who and in what order.
I'd love a lot more spontaneity and excitement, but my DW is very vanilla and never suggests anything other than sex 101 and if I ask her to try something, goes quiet or looks at me blankly, making me feel like a pervert or some deranged idiot.
We lie next to each other, always in bed.
I have to wait for her to initiate to give the signal that it's game on, as if I do, 9 times out of 10 I get rejected, so I never bother as the rejection hurts when it's so frequent.
She will start by touching my nipples as she knows I like that (amongst other stuff, but variety is not her strong point, despite frequent requests and hints - I have to directly ask for stuff time and time again, it never sinks in for next time) then I'll touch her breasts and maybe suck on her nipple a little, followed by stroking or rubbing between her legs, which sometimes after 20-30 rather boring minutes of one way traffic results in her having an orgasm, but not always.
DW might on occasion touch me without me having to request this,, and if she does, it's tentatively and with little enthusiasm and very poor technique, which does very little for me so we then get down to PIV.
PIV is normally me on top for a few minutes, then either she will go on top - laying flat against me (not riding), or if she's recently showered, I'll go from behind. After a few more minutes of either of those positions with no encouragement, feedback or enthusiasm coming back my way, I'll get bored and dispondent, so just try and imagine something far more exciting, or pretend I'm with someone who is really into it and enjoying themselves, then I'll try and cum, however there have been times when its been such an underwhelming experience that I just give up and masturbate later on when I'm alone.
