Yes, as it dries, but not as much as cotton. And when wet, it stinks. Here ends Good Housekeeping. I concur with Lurkerspeaks. I've had 2 such friendships, each lasting several years: the first was with a bi personal trainer 23 who loved to suck cock and swallow a mouthful of cum; and the second was with a blond muscleboy 20 who loved to have a cock in his ass and he would ejaculate without touching himself as I unloaded in his mouth. Each received a small amount of 'help'. Over 2-3 years, the trainer became an enthusiastic kisser and wanted me to invite others to use him, while the blond muscleboy became more affectionate, wilder in bed (he liked bondage) and stayed for longer periods of hours.
