In a way, giving a BJ to your man is similar to your man listening to you: one can live without it, and often the "giver" is not really keen (believe me, most men find "feminine talk" boring or inane)... and yet both are a sign of love for your partner.

So, next time you do not feel like giving a BJ... think how much you appreciate him listening to you. I assure you he strives to do that, because he knows how much it's important to you. Now, can you...?

If you reply to the above with "Yes, but...", chances are you're much more into receiving than giving. Not good news for your love life. ;-P
