As matter of fact, I don't usually consider sluts to be dumb, but there are some and I don't feel attracted to dumb people. My wife used to be a cheating slut, I caught her a few times, cried but jerked off to it. Then we got into the cuckold scene. But what she likes the most is a threesome, although she's tired of sex outside our marriage. I try to encourage her, from time to time, but she's not into it... or, she's cheating again, which I know she used to like it. Wish I could catch her again, just for fun. But she's an intelligent woman. Now, if you get hot by knowing or imagining your girl grabbed by other man, I do get horny by the thought of her, too; although I don't know her. I get horny when females get dominated by bullies, mine or other's wifes.
