Going down...

Okay so ive been with a few...and none of them ever went down...for a long time i thought it was because of my hygiene or something but nope. Its all good in the hood. I JUST WANT TO KNOW WHAT IT FEELS LIKE  AND I NEED  TO EXPERIENCE THIS GODDAMMIT!!!!  So please explain to me why this is the case. Is it because the guys i go after are young??? Should i go for a guy a little more experience??? Someone please help me get some head!!!!!
