I've been checking out personal ads online lately. It's fascinating reading what people put up for their standards. Body size is a curious one.

Body size is indeed an interesting topic when it comes to personal ads online. People's standards tend to fall into one of two categories: those who specify a certain body size or type, or those who say they don't have a preference. Some people may specify they prefer slim/athletic types, while other might specify larger/curvier body types, and some may leave their preference open-ended. 

The reasons behind these body type specifications vary greatly — some may be indicating a desire for certain health conditions, some may have cultural values behind it, some may be indicating an interest in BDSM or certain role-plays, while still others may be looking to meet people with a shared appreciation for bigger bodies. Whatever the reason, the discussion of body size in personal ads can be a fascinating insight into people's individual preferences and ideas.
