It is not thin but Slim or I would say with some flesh on their body...not just bones.. You should feel like geting physical with that person..
You should have flesh where ever required.. that makes you sexy.. I hope you got it....
At least man/boys are attracted to girls/womans with bigger breasts and sexy thighs... (I mean there is a limit after which you are not sexy but fatty.. very difficult to draw the line.. Depends upon individuals)
The models or so called todays girls actually think that man like thin woman but the fact is opposite ..Man like Slim and healthy womans.....
