Nude pictures

Why is it that there are those on this site, a nudist site that have no nude photos in profile. We love to trade pic with willing females and couples by e-mail, we do not share pics that are sent to us, they are for our private enjoymen only. When they agree to trade, we always send first as a show of good faith but what is with agreeing to trade personal pictures on a NUDIST site and only sending pics of yourself fully clothed. If you are ashamed to show and enjoy nudity maybe this ain't the place for you. Rant is over, now I feel better. Thanks for listening. Lynn
