No...it isn't importart at all.
Actually I prefer no TV...music instead.
I have been in situations where the lady had porn on the TV when I walked in, and all it does is put me in more of PSE mood. If she wants to watch and/or listen to porn...then fine by me. Get ready to break a sweat!
There have also been a couple a times when I walked in and she had the news on...or a basketball game. Even the Lifestyle channel LOL! Sometimes if we really click, we can drown out the TV by just being into each other. That is always a possibility.
Not to drift off topic, but ...It isn't any secret that some ladies don't really enjoy DATY. It does nothing for them....but WE like it!! One time I had this girl in K9 and was really enjoying myself with what I thought was a good round of DATY from behind. I hear her giggle, I look up...and she's laughing at the fucking TV.
Total...BUZZKILL!! She got a NO recommendation.
