I am assuming that she is of legal age to do so, and the main motivation is money. The reasons to get into adult entertainment vary from person to person, but the glaring fact is that there is a promise of some significant cash to be made, in very little time. Some people are also very proud of their bodies, very open with their sexuality and the opportunity and ability to share/express those, get paid, and even enjoy their time and notoriety? Well, for some, that is also an interest. I've known people in the industry who feel very empowered, very in control of their own lives, and may be exploring their sexuality, fantasies and discovering their own limits and if they can surpass those boundaries. All of which are very personal and private matters that only the individual can decide for themselves. You are concerned and clearly care about your sister. That is good. Don't lose or put your relationship with her at risk. You should make it clear to her that you understand it is her decision to make, but because you care about her and love her, that you have the 3 main concerns that anyone has for someone they care about. When you care for someone, the 3 most important things that you want for them is to know that they are safe, that they are healthy, and that they are happy. Anything else is secondary. But their safety, their health, and their happiness? Those are the things that really matter when it comes to someone you care about. So, in the interests of her safety, her health, and her happiness. I would say that it is important for her (and you if she will share with you or include you in the process) to clearly know and understand how such a career move would impact or potentially risk her safety, health and/or happiness. First off, has she done any research? Does she know people in the industry? What aspect of the industry is she looking into? Is she undecided as to her limits? How long she plans to do this? Has she thought out what she is capable of doing, willing to do, may try out and what are her "hard stops" and absolute "will not go there"? Such research may be uncomfortable for you, but it shouldn't be for her. If she is considering a career or even a quick stint, she can't be squeamish, coy or hesitant. She will need to be blunt, open, honest, and self-assertive. People in the industry do not have the time or the money to waste on someone who doesn't know, isn't sure, or can't decide. As a matter of fact, there are some people in the industry who are on the lookout for people who are uncertain, over-whelmed or unable to assert themselves and they will manipulate and exploit such weaknesses. So, you want to be a good brother? This could be difficult. But if you want to be a good brother, you will need to not make it about you, about your family or about anyone but your sister. This is her decision to make and if you make it clear to her that you are in her corner, but are there because you want to make sure that she is safe, healthy and happy, then she will probably appreciate your efforts to make sure that she makes informed and responsible decisions based on facts. Best of luck to you, to her, and to your family.

What is "adult entertainment"

Pretty arrogant to suggest "I think I'll do porn" without providing a picture. It's not an easy field to get into properly and without just being casting bait.

If she never plans to have kids, morals, or respect she should go for it!!!!

I'll watch her in support
