This seems like an ancient obsession. Many pagan religions quite literally worshipped the phallus - complete with huge statues, etc
Could be this deeply engrained in human nature.
Love having mine worshipped (I remember one girl - I had her bound and handcuffed on the bed while I sat on a chair in front of her, a big brass ring around the base of my cock, a candle on each side of me the only illumination . . . it was hot and got hotter once I allowed her to touch what she was longing for . . . ).
I also like the idea of worshipping one (obviously the bigger the better)
