Let's address the elephant in the room shall we... yes, I'm male. I've been photographing boudoir and maternity for over 10 years. Your safety, well-being, happiness, and most importantly comfort whilst in the studio is my highest priority. It is for that reason that we adhere to the a strict Code of Ethics.
We will have at least 1 female on set to assist with every shoot, usually 2. With these amazing women on set I should never have a need to touch you, and so my promise to you is that I will never adjust your hair, fabric or dress without your express permission, each and every time. Many clients, after a few times of seeing how I step in to help my assistants, give blanket permission for the rest of the session. You do not, ever have to give permission and I will verbally direct my assistants. I encourage you to speak with our previous clients and/or to be bring your own chaperon if that would make you feel more comfortable.
One model said to me "You're the only photographer during my 15 year career that I've ever let adjust my clothes during a photo-shoot", I was both humbled and appalled by this statement. This was of the reasons I became a Consent Guardian and teach consent workshops in a non-judgemental, if you haven't been taught, how can you know, kind of way.
