hi RctBogus, hope that you are still checking your post.
So you have replaced sex with golf, video games etc in other words your sex life wasn't enjoyable, so I wonder why the both of you hadn't tried to spice it up, and actually I have googled exactly this and the suggestions are enormous on the net, but for me well I'm 61 and live by myself so it won't do me any good, but for you at the age of 29 I would have talked about it to my wife/partner even though it maybe embarrassing to begin with, because it assumes that she is not performing well, well not really it takes 2 to tango.
Actually my sex life was not the best after 25 years of marriage and I was too scared to raise the issue,so what I have just said is thrown out the window.
Now with this new job it's exciting for you, a new challenge so you're just replacing your sex with meeting these new mates and what you can do and what you can't do, so it seems as though this has replaced or taken over from having sex.
I realise that she has lost her mother which I'm so sorry for and is also trying to rebuild a relationship back with her dad so this does take a toll on any relationship, but if she is what you want for the future you need to talk about where your life is sitting. Geoff.
