i know how you feel. it started when i watched porn and saw a huge one and seriously thought i'll grow up with one haha.
Then i dated a girl who dated a very hung black guy. After she told me (phone/internet.. never i person) I couldnt' stop picturing her and her ex. That lead me to some cuckold fantasies and i honestly want to like hold one and get one hard. i think i would hook up with a really hung black guy for like a one night thing.. kind of a wild fantasy of mine haha.
A huge cock just seems soo masculine it kind of makes me want to be submissive even tho im a pretty masculine guy myself.
