I don't think it's necessarily psychopathic. I was raised to be such a prude so, I don't feel all together comfortable when people are overtly sexual in public. I'm also not into casual sex. While I don't care what other people get up to, sure, hearing guys rattle on and on about sex at work made me grateful I don't have a dick that does so much of my thinking. It's got to be really distracting!
I think it's more about different expectations in life. It's partly like listening to someone ramble on about a subject we're not interested in. The trouble with sex though is that you can be judged for your perspectives and personal experience.
Even with relationships, there can be a cynicism observing them I think. I don't really like overhearing 'couple talk'. Sometimes it's just nauseatingly saccharin. Other times, it just doesn't sound sincere or, it seems possible one person is being emotionally mannipulated. In those instances, I also tend to feel- I'm glad I dodged that bullet.
Perhaps it's maladjusted. I wouldn't say it was socio or psychopathic though. For me, it's more a relief that I don't even want all that now.
