If a girl mentioned she had slept naked before would you be instantly turned on?

You'll have to be very suggestive with it.

If he's apprehensive like some guys can be, it'll do nothing of him unless you insinuate some possibility of him joining in on the fun.

At least mildly so. Especially if you were on the phone to him from your bed at the time.

if she just mentioned it , it would depend on how attractive and or honry I was at that moment, but this is different he told you to TRY it and then you go do IT. That's hot, instant turn on for him :)

Hell, yeah!
Probably waaaay more than you can possibly imagine (his hormones are raging way more than yours are - if you're both "average teenagers")
Guys get turned on seeing the crotch of a tree. We'd mount the crack of dawn if we could.
Good stuff!
You have so much more control than you probably know. Be nice though. Our hearts can be extraordinarily tender and easily broken.

I think its a big turn-on and not only that you'll probably keep his mind wondering.

I think its very sexy but my girlfriend won't sleep naked because she says her boobs hurt in the morning if she doesn't wear a bra or shirt

Excuse me. I'll be right back.

Yes I believe so.

The thought of a girl sleeping naked is extremely arousing, and most guys I think would be instantly turned on if the girl (as long as she were somewhat attractive) told him she slept naked.

I know I would. : P

It is.kinky.

Yes. Guys get turned on over the littlest stuff lol
