I really like the aroma and smell from a cock. It has this very exciting and pulling feeling that gets me very wet.
I do however have a small routine and kind of fetish, when I have the chance, of thoroughly washing a cock before having a more intimate and fun relationship. I learned this from a man that like for me to wash his cock first before sucking it and I maintain this habit when I can so I will tell my routine.
Of course we are in the shower and talking and I ask if he let me wash it. I put soap in my hands and rub my hands a lot with soap so my hands become very slippery with soap.
I grab the penis, usually not hard, and begin to stroke gently. Immediately the penis becomes hard because it is like masturbation and very slippery. I make sure to get much soap and slide back and forth. If it is uncircumcised, pull the skin much back and close hand around head of cock and really rub it to remove all the dirt between.
After the cock is very hard, I put more soap on my hand and go to wash the testicles. I get and do same routine but more gentle, washing between the thighs and under the cock.
Usually i remove soap with water and repeat the treatment. The man is already ready to get out for fun. Sometime I start a blowjob in shower with the very fresh clean cock before continuing to bed.
