Hm...yes, I personally don't find [u]very[u\] young heroines to be sexually arousing, simply because they aren't as fully matured as they could be. For me, I tend to lean toward the sixteen year olds and higher, as they are still young and innocent, but are quite mature (physically and otherwise).
As for that comment redEva made about the lecturer telling about the joys of psycological screwups involved in bdsm, I think that's crap. The concept of seeing that very attractive female on the street tied up and naked and being assaulted doesn't make me a weirdo (though I still wouldn't advertise it via shouting it from the rooftops). However, I wouldn't be surprised if the two [psycological badness and bdsm] were related, but the other way around. An interest in bdsm doesn't make one a horny psycopath that steals women (or, in cases other than mine, men), but I wouldn't be surprised if the lonely kid with no friends and cuts himself with knives every night (exaggeration) DEVELOPED an interest in bdsm. If placed in those shoes, I would find it very comforting knowing that the "super-hot female that pretends I don't exist" is bound and gagged and about to be punished by me for being a bitch. I wouldn't be able to do it in real life, but I could get ideas from bdsm stories/pictures and ACTUALLY take this girl. Now, to sum it all up, I don't think that an interest in BDSM makes someone abnormal; instead, I think that an abnormal person might coincidentally have an interest in it, because it gives that person a feeling of satisfaction or something else. Is this making sense? Because I only woke up 45 minutes ago and I'm not even sure what day it is.
