I completely believe they destroy your sex drive.
This is my reasoning why -
What actually makes you horny, from what I understand, is anxiety (a form of "sexual anxiety" or "sexual tension"). For instance, sex FEELS much better when you are anxious. And when people get really horny, they tend to get irritable and anxious... cause they want to have sex. But paradoxically, if you become too anxious, you won't seek out a sexual partner.
So when you take something that masks that anxiety, you effectively lower your sex drive.
And here is more anecdotal evidence to support this idea.
I simply can not masturbate at night *after* I take my benzos. I can't have sex. I have 0 desire to.
But as my benzos are wearing off, between 6pm-midnight (I take them around 2am) that is when I feel horny. Its when the pills are wearing off.
There have been so many times I've had porn on right before taking my dose, I take my dose, have to search for an hour or 2 to find that 1
magic video, nothing does it for me, and I just turn porn off and lose the desire.
So I completely, 100% believe that benzos lower your sex drive.
Lets not forget, they basically tranquilize your body. They numb you. I'm not saying you can't have sex on benzos cause you can. I'm saying
it feels 10xs better to do it BEFORE you take your dose. Not after.
