To be honest, i do find it an intriguing smell. I've met some girls who said they got turned on by smelling the head of my cock with dried precum... I personally prefer the smell of panties, especially those of a woman ovulating...
My friend, you don't even need to ask. I would worship those holes with all the lust in my mind... I want to sniff deep to smell their natural aroma and then use my tongue to massage and explore every inch of those holes.
