Well sex will be a bit diminished after awhile and considering how much you were having I can see where after awhile it would feel like a chore if you weren't enjoying yourself.
If you don't mind.
How old are you?
Do you feel aroused but just not with him or not at all.
My thinking is if your aroused but not enjoying sex then maybe its time to change things and bring in something new....try different places, toys, porn, role playing, whatever your mind can think of.
Completely baffled by a backward indication
That an inspired word will come across your tongue
Hands moving upward to propel the situation
Have simply halted
And now the conversation's done
I am the EgGmAn
