WELL, if your question is a genuine one, my answer would be this:

What is 'wrong' with you is that you are completely stressed and overwhelmed by a whole host of current negative events. There seems to be very little support for you, and both home and work are currently very stressful environments, affording you no 'safe place to land'.

I can sort of understand the oral sex exchange thingy... it is 'easy' and quick, and would give you one less stress in your life (by getting the lawns mowed.)

HOWEVER... don't go there, girl. You know that, right? I've read other things you've written about your hubby, and.... don't go there. If you do it once, he will expect it as his right.
In the short term it may get the lawns mowed, but you know (in his eyes) the lawns are going to cost a whole lot more than that one little bj, right?
