The TV in the bedroom is to help me fall asleep or to give me the weather report while I’m trying to force myself out of bed in the morning. Mostly, my husband and I watch in the living room - him on the couch, me on my recliner with a cat and/or dog on the raised footrest.
We also have a set in my husband’s workshop and I have a small one in my pottery studio, but I rarely turn it on.
Since this is about lifestyle and not the content what the TV is showing, moved from Cafe Society to IMHO.
Our family always just had one TV, in the living room, until a couple of years ago, when we bought our giant LCD TV. Then we moved the old CRT one into my older daughter’s bedroom, because it’s the second biggest bedroom in the house and (more importantly) she was away at college and thus not able to protest. She also has the VCR and the oldest game system in there, and she was every bit as delighted as you might imagine to come home and discover we’d made that gift. 
Yes, it is a small ancient one. I also have a VHS/DVD combo player.
I use the TV and it for two things:
For watching the 11:00p.m. news in bed and for watching porn on the weeks when my kids are at their dad’s.
Yep, we have a TV in the bedroom. It’s a 47 inch LCD in an armoir that we close when it’s not on. These days it’s used exclusively for Netflix viewing as we have given up our cable.
We have eleventy billion other TVs throughout the house but, besides the one in the exercise room, which is rarely used, the one in the bedroom is the one we use primarily, and it’s on pretty much whenever we’re in there.
I have difficulty sleeping (and falling asleep) in complete darkness and silence, so the TV stays on all night. The problem is because we no longer watch broadcast TV, when our Netflix program ends I’m engulfed in silence and darkness again, which sometimes wakes me up, prompting me to select something, anything, just so I can get back to sleep.
I had one in the BR back when I was single but only watched it when I was alone. Since marriage, we have never had one in the bedroom, only the main one the living room and a small one mounted in front of the treadmill in the hopes it will encourage us to exercise more.
I just realized that I didn’t answer the last question in the OP, but missed the edit window.
No, having and using a TV in the bedroom doesn’t have a negative impact on our lives, sexual or otherwise. I’m not clear how it would.
Heh. We added one in our exercise room, mounted to a swivel bar on the wall, for the very same reason. Answer? It doesn’t. 
Oh, we use the exercise room although not nearly as much as we should, but the TV doesn’t give us any motivation to get our butts in there.
The bedroom TV is very rarely on except for the morning news.
I do have a TV in my room but I haven’t turned it on in so long. If I want to watch something, I just put it on my laptop (I don’t have cable, and Netflix and Hulu can go on TV or computer).
I don’t have one in the bedroom. I can’t imagine being able to stay awake while watching in bed. It’s hard enough not to doze off sitting in the recliner.
Yes, married and we have a 36" SD CRT in the bedroom. It’s where 99% of the TV watching occurs, even with the 50" plasma in the next room. And no, I have no sex life; none for over 5 years.
One TV, in the living room. Used to have one in the back room, too, but it went away a few months ago.
Wife and kids watch it; I don’t.
We have a 25" CRT TV in the bedroom. We hardly watch it now, but sometimes. We used to watch it more, but the local 10 O’clock news got worse and worse, and we don’t watch that any more, so we don’t turn the bedroom TV on much. ETA: We have an HDTV in the family room that gets used a lot, for TV and video games.
It never had any effect on other bedroom activities.
TV in the bedroom and in living room. I’ve had a TV in my bedroom since I was 16 and able to buy one for myself (in the 60s, not like today when so many kids get them at four or five). I do almost all my watching in the bedroom and he does his in the living room. Our tastes are different, and I get dizzy at how quickly he flips through the channels.
Another person with a CRT in the bedroom. It’s an old TV/VCR combo unit to give you some idea. The cable for it only gets about 20% as many channels as the TV in the family room gets and we only use it if someone is bedridden, someone just HAS to watch program B while the other TV is in use or sometimes the wife has it on when she’s winding down to sleep while I’m still up.
No TV in the bedroom. Hell, we went for years after the digital conversion without bothering to hook up the free converter box, so we didn’t have any live tv, just DVDs.
Nice big tv in the living room. That’s where most of the TV viewing happens. Small LCD tv which needs to be replaced in the bedroom. When we feel like snuggling under the covers while watching that’s what we go. Our sex life is just fine.
hogarth’s answer is pretty much mine, except I know for sure the TV in our bedroom doesn’t have an affect on our sex life.
Haven’t had a tv in the bedroom since I was in high school, where it didn’t affect my non-existent sex life at all. We don’t watch enough TV to make it worth it, and no late night shows, and we want to reserve the bedroom for bed activities, in other words reading.
