I think "out of line" is a little strong..but the most I have left a clothespin on my nipples was 20 minutes. My Sir made sure I understood that time limit, where blood restriction, is concerned was understood before I applied them in any task he gave me when involving them. I never went past that time limit just because of the fear of damaged skin.

I have noticed, as others had mentioned, some pins even with in the same package, are tighter than others. Also, different types of clothespins are "evil". I've tried plastic ones that hurt like hell and, in my opinion, caused more blood restriction. Just becareful, and watch. It is your responsiblity as well as his to pay attention, especially since yours is an internet relationship. As IDdawg mentioned, color can't be seen as well as if he would have been there with you.

Best wishes
