Large Labia? Innner and outer...Fantastic.
What a turn on.
When you are copulating and they really swell up they not only grip more, but look even more sensual, because as with the unmistakable male erection telling the girl what the man is thinking and wanting and the effect she is having on him, the swollen labia tells the man the same thing about the girl, and that is an even bigger turn on, especially that he is pleasing and arousing her.
Thus success breads success.
Remeber nature and evolution have provided both genders with a set of tools to do a job and the better that works the better the result. So leave well alone and learn to use that, that you are provided with, as any skilled musician would play her instument.
To the girl with the large pelvic bone. This is also a point of beauty it is and has for millenia been known as the "Mound of Venus", and for good reason It not only enhances the Vulva, rather like a good picture frame does with an oil painting or a woman's hair does for her face, it can be used to great effect by you with coquetish movement, and physically on your partner when having intercourse. You must learn to use your body, every part of it. As I said before evolution and your genes have conspired to give you an advantage, so use it.
Just forget any idea of changing anything, especially surgery, my knowledge is, that it is to a man's eye a sight of beauty and bliss to be adored. The real problem is few men will actually say anything about what they are feeling. But suffice it to say the very obvious physical effect you are having on him, will give you your answer, and his unspoken one.
