So, I'm 18, I wear a 36C, and my breasts are kind of.. Cone-shaped. And they sag a little. They almost remind me of man-boobs, but I'm only slightly overweight, close to average size for a woman my age and height. All other boobs I have ever seen are round and perky, and mine are just.. Blah. I feel really self-conscious about it, so I always wear a slightly padded, underwire bra to give them a more rounded structure, even when I am sleeping. I hate being naked around my boyfriend, but when I am naked around him, or when we shower together, I try to cover up my breasts with my arms. Are my boobs normal? Does anyone else have this problem? Please help me feel less insecure. \:

Cone-shaped boobs are really normal - I have them, as does my best friend. I wouldn't reccomend wearing a bra in bed though, it might put strain on your neck, as well as opening up the oportunities for cardiac (heart) problems to develop.
As for being with your boyfriend, I don't think guys even notice things like that. I remember that when I met my boyfriend at, I'd never had a boyfriend before, so I was a little self-conscious, but when the time came for him to see my naked body, he just got on with what he had to do and still loved me...he still does, 8 years later, my husband and the father of my kids! I guess that with the men, they don't think about the cone-shapes or the wobbly bits or the marked bits; all they think is "hoorah! A naked woman is stood in front of me!" And I suppose that must satisfy them!
Don't worry about breastfeeding.
I had twin boys at 18, and bearing in mind I had cone-shaped boobs, I managed fine! The nurses gave me a little tutorial vis a vis positioning and everything (although that may have been because they're twins). They're now 5, and I actually have nicer boobs than ever before! Breastfeeding enhanced my old boobies! I'm 24 - so young - and my boobs aren't as cone-y as before.
Don't worry, boobs come in all shapes and sizes!
Feel free to message me with any follow up questions, or reply!
Good luck!

Don't worry about the cost either, your boyfriend WILL pay for the op.
