For me it was a three step process,
step one was raiding my families clothes hamper and smelling and tasting the panties i found in there. i strted to do this when i reached puberty. i guess i just wanted to be as close to pussy (any pussy) as possible.
step two was how i felt when i stuffed my mouth with panties and wrapped them (or bras) round my head tightly so i could hardly breath. i started doing this after a few months of raiding the hamper. gradually i realised that it felt so good to have my sense of smell and taste and even my vision filled with used panties and bras. the scent and flavour seemed to seep into my brain and the lack of oxygen made the whole experience seem profound.
step three was finding on the internet that there was a fetish called facesitting.
for me this was like a dream come true. it all seemed to make sense for me. ofcourse i wanted a woman to sit on my face !!!
since then ive been used and abvsed by scores of women of all ages and races and ive loved every minute of it.
how about you?
