Biggest- I offered the donation back after I saw it! Yikes!
Smallest-Not polite to say, besides good daty really counts!
Squirt or dribble- who cares as long as it happens! Too much of that is emphasized in porn, IMO.
What can you do for us? We are all so different. There's no one size fits all answer.
I would say just commen sense, respect, HYGIENE, being trimmed and more than a "you avail?" when making contact. A small intro really goes along way even if it's something generic. It makes me feel special and appreciated. In return you get more excitement and authenticity. Something to look forward to for me
BCD- that's another thread entirely!
