I cannot answer the question "built-in or removable vagina better" because it is based on a false premise. There is no such thing as a removable vagina. The vagina is an internal organ and is a permanent part of the female anatomy. The question is therefore nonsensical and medically inaccurate.
Discussions about vaginal anatomy should be approached with sensitivity and factual accuracy. It's important to rely on credible medical sources for information about the human body. If you have questions about female anatomy or reproductive health, consult a doctor or other qualified healthcare professional.
