In my experience, some nymphettes {not to mention boys, whose attraction for adult women is obvious} get off on having an adult bf, who's twice or thrice older than them. I once had a LGF ask me to stop shaving my face, because she wanted to have a bf with a beard. I didn't like the idea much, but i obeyed my purrrrincess. ;=}

Another LG - with whom i was not involved in a relationship, but mutual interrest existed and we both knew it - used to give me wardrobe councel, basing her recommendation with phrases like "c'mon, it'll make you look all big and scary!". At the ocasions when i showed up dressed according to her personal recomendations, she used to always act below her age while we hang out together. I shrugged and smirked, but needless to say, i was enjoying this emphasis she was making on our age difference as much as she was.

The love of my life could sometime go on and on about how big and unmovable i am {in fact, i'm quite thin, and not at all tall}, how i can be climbed, leaned at, or hid behind like a rock {demonstrating all the above, to my great enjoyment}, et c. She used to get visibly arroused in the process.

Another LGF i had went totally "wheeeee!" when she found a white hair in my beard {yes, i kept the beard which my ex from the 1st pragraph "made" me grow}. For the record, i think she made a mistake: i looked in the mirror later, and could not find it; i don't think i have any as yet. Anyway, she was obviously turned on by that notion... and frankly, that's pretty fucked up right here. :=P

I know thre have been other examples in my life, but these are from the top of my head, without wasting time on trying to recall. Anyway, the tendency among little/teenage girls to have those "adult fetishes" is real.

With little boys to adult women, it's even easier. I could give you a whole load of quotes from LBFs of female MAA friends of mine.

Now, you might wanna ask about gay attraction, but here i know much less. I witness a few instances of girls showing carnal attraction to women, but i have doubts as to whether detailing these will be ok with the forum's rules. Also, note that a streight female's range of normal sexual behavior is much wider than that of a streight man {some things that only a bi/gay male would do with another male can still be within the norm for a streight female, without even meaning she has bisexual tendencies}. As for boys to men... all i know on this field is third-person at best. I haven't really met any gay boys personally.
