Miscellaneous | How to ultimately get started…

Hi everyone! This is my first post. So please be easy on me if it is rambly or in the wrong section. (Still trying to figure out how to navigate the website). So I am completely new to the scene. I am a young female without a partner. I am a virgin completely. I have never expiremented with any fetishes or kinks because I simply don't know where to start. I am worried if I just jump into it I will do something wrong, and will ultimately decide I hate everything to do with them. Now I am not sure if I even would like these, but they seem fun and interesting to read about! I get pleasurable thoughts reading posts about them and envisioning myself in these scenarios. Some of the things that I would like to try are suppositories, enemas, and diaper-wearing. I live with other people that I don't feel like would be very accepting. I am also interested in stuff involving other people like medfet, BDSM dynamics, and acting younger than my age. However I want to learn about myself and what I like before exploring those further. So I just wanted to know where a good place to start (by myself) is? Like would suppositories be a good first exploratory step? Thats kinda what I have been thinking but I have many questions like can you buy them at a local pharmacy like a CVS? Are they safe to take when they are not needed physically? Are there restrictions to buying over the counter ones like age or identification needed? How long should I need to myself for the process etc.? really I just need a lot of details because I am a complete newbie to this haha. I have no childhood experience with anything like enemas, suppositories, or rectal thermometers.
