I suggest you seek the advice of a suitably trained and experienced plastic surgeon. You do not make it clear why you want breasts like this or any information about your current appearance. It is unusual for a man to request 38D breasts unless it is part of transitioning to be female. However, I have been asked this before outside of a wish to transition. The 38 is the circumference of the chest so this is not normally changed by surgery. Your request needs detailed assessment in person by some who is suitably trained and experienced.Best wishes
Men asking for larger breasts is not uncommon. Depending on the type of look you are seeking there are a range of breast implant types you could choose from to achieve your goals. Seeking a surgeon who has experience placing breast implants in men and smaller chested females
