When I initially signed up my interest was in looking and I had no plans to post photos: just browse for a few days then leave. That was 5 years ago and I started posting almost immediately.
I clearly have an exhibitionist streak but not everyone has that. There are two elements to this site, posting and looking and we all combine those in our own ways. There are more annoying things than people not posrpting.

Half the appeal of this site is showing of your own cock (hence the name of the site). It's their loss if they don't, but at least I get the enjoyment of them looking at mine and commenting on it.

There is a setting:

Membership.....Edit account settings.....My pages can be viewed....

Mine is set so that it can only be viewed "by members with photos".

The site is called "Show Your Dick" not "Guess What My Dick Looks Like".

If the person has private pics, I'll suggest that I'd like to see them too. They've always obliged by sending me a pic or two, or making me a friend so I can see. It's worth the effort, have seen some fine pussies and cocks this way.

What is even more weird is that some people can't use words such as pussy, cunt, dick, cock, etc., on this sex site, but they speak of vaginas, genitals or penises.

Even though the site is called :show your dick/ cunt " and not "exhibit your copulatory organ if you please ".

Some guys are afraid of other people (e.g. wife) finding cock pics on the phone or computer. They must not trust themselves to competently cover their tracks.

Some don't like sex photos. They like photos of their favourite scooter rather, for example.

people are here for different reasons, some like to share pics, some like to look at pics, some want to talk dirty, some want to read stories of what others sex life is like. maybe it should be compulsory to add 5 pics of a sexual nature to enter, especially since it is called 'showitoff', showyourcunt and showyourdick, as much as l don't like close up cock shots, maybe there should be a minimum requirement to enter and perv on others, share and share alike, add pics to see pics, there are so many empty profiles, its annoying to open a page with no pics, or now public pics to see *lix*

I've corresponded with those who just don't have the technology--pure and simple.
