Hi Karen,
As far as what to plainly address or say, here is what I did.
I asked him what his ideal sex life looked like in terms of frequency. He replied twice per week. I asked if he would be willing to work towards that and make it a priority in our lives. He said yes.

It sucks to have to pin down your mate on WHAT ARE YOU WILLING TO GIVE ME because you want it so badly to come from a place in which they want to do it, as opposed to doing it cause they're under the gun.
But you have to start somewhere, right.

Finding out what type of frequency even sounds good to him might be a good place to start.

From your description of your guy, I seriously doubt the Catholic background has one iota to do with your situation. I think that he (like my H) might just be a persnickety, anxiety-riddled fella who can't turn his mind off long enough to think to himself, Dude! She is HOT!!!!!!!!

Anyway, keep thinking of specific questions you want to ask him and make a mental list of them for your appt.

Best of luck and let us know what happens..
Honey
