he offers to keep going, probably with all the romance in his voice of a mechanic who is doing an oil change? lol, that'd make me mad too.

It sounds to me like you have a couple of issues going on there.

First, it sounds like your getting over the 'honeymoon period'. its very normal for a relationship to settle into a somewhat boring routine, and lose some of its romance. it happens to everyone.

Then, you mentioned how you were raised. I don't know what happened to you as a child, or how you were raised but it sounds as if you might have some issues with healthy guilt free sex. That might be something worth exploring on your own.

Lastly, some advice i give everyone is COMMUNICATE. tell him how you feel, every last feeling. Lynn had it right when she said to tell him what you want him to do. Speaking as a man(i'm a tranny so, im kinda half and half) , we just don't get it most of the time.

If you resent him the sex will be terrible. terrible sex leads to more resentmet. you will resent him until you've both had open honest communication. Its a nasty slippery slope.

I hope this helps a little and I hope things get better for the both of you.
