hi, 20yo male, found this site today and i pretty stoked, gonna start uploading to my tumbler as well. anyways onto my experience. iv done water inflation, it was great watching myself in the mirror expand to a size i never thought i would be, enjoyed it so much i pleasured myself by looking at me in the mirror. but gravity was against me, every time i did water inflation i could only hold it in for a few minutes then i would have to let it out so i stoped doing that and moved into airinflation, which is so much easier and better i find.
