Of course there is! Actually, having a quickie can be pretty exciting! What I was trying to convey is that in my case, the "just have sex" comment came across as she did not want to, but she'll allow me to have my way with her. It did NOT come across as she did WANT it but just quick. I think the difference may be that if the guy's initiating all the time (like I was), then a comment like "do it quick" comes across wrong. That's where W and I had our misunderstandings I guess. Especially over the past few years, very few times have I felt wanted by her. The last time was actually 3 months after the bomb, when I had been away for 2 months for work....
Here I go again, rambling off track about my own stuff. I guess my point would be to make him feel wanted on a regular basis. That makes it easier to accept the occasional "i'm not in the mood and tired".
I might be coming across to you as very persistent with trying to make my point, but this was one of the major things that caused misunderstandings between my W and I.
