like you I have small breasts 30A and 10mm long nipples. I am now 62yo and have not worn a bra for so long I can't remember the last time. I mostly keep my pubes short and trimmed and as we live on 10 acres I prefer to go nude at home and have no tan lines. my man has never worn any underpants and I love seeing him swing free.
I have always loved tiny tits on a woman. Most men like women with larger tits but I have always been attracted to the women with small tits. I think small tits look so much more natural.
