Small to medium, in my opinion, i don't think that you have to have giant boobs to be a woman. Im small, and im proud of it!
For myself I like boobs to be between an A or B cup. Large breasts may look alright at the moment, but add 10 years and they will become extremely saggy and stretched. No thanks! peace
Well, I put small to medium but I'm a weird guy. I also like guys and love to run my hands over firm rounded pecs and play with their stiffened nips. My wife had a good hand/mouthful and I was always happy playing with that. For a while, years ago Playboy magazine was running pix of Guernsey sized women. I did not find that appealing at all but it seemed to be what the average Playboy buyin' guy wanted.
I like them smaller myself. Don't know why just do. One thing for sure they have to be real. Don't have to be perfect, just real. Actually when you come right down to it, it's the nipple that counts! I also like larger labia.
34B ... I think just as many men like small breasts as large. I also think there are just as many leg men as boob men.
