This is wrong on so many levels. Friction makes you feel good, so too much lotion removes almost all of the friction and you feel almost nothing. There's no fun in that except for tightening and widening, but all the positive feelings just aren't there.
Also the thing about the lotion and the shower is wrong, just as Hounder said. There are many products, which even state to leave the skin wet before applying. Naturally after the bath/shower.
