Anna, there is no such thing as too big, any more than there is a cock that is too big. You are so fortunate to have lovely large labia, and also I must assume you are talking about your clit (the part above the labia). As you can tell from reading the comments on this site, and looking at the photos, not only do many women have larger, thicker labia, it is a true blessing to them. There are so many women who have commented on here, as you have, worried about the size of their labia, and then with a little education they come to understand what a true blessing it all is, and how sexy they appear to their lovers. The very bulge in your panties that you mention is extremely attractive to most men, or women who love women. Once confidence is gained, you are able to enjoy some truly amazing sexual experiences, which are enabled by your larger labia. Check this site out thoroughly before you decide to do anything so foolish as to have surgery. You would be losing one of the very best parts of yourself forever, and paying dearly for the privilege.
