Dude, this problem won't go away...this is what ended my marriage...sex is very important! Especially when you are a horny mofo like me...it won't last, you will lose your mind.....
The four year old is in another room with the door closed? Sex shouldn't be an issue, then. What does she expect people to do when they have their kids all the time? I think this is totally unacceptable, sorry.
Hahahahahahahahahaha I have asked my hubby to do that before... He said 'why beat off when there are so many holes lying next to me??'.. I couldn't argue
