How to shave the important spots?

I just got home after wearing my small plug for the whole day for the first time. It was great for a while but after a few hours, my hair got caught and it just felt uncomfortable from there (and gross). The same thing happens with my cage. I'm a naturally very hairy person, and it doesn't help I've never shaved before. I'm not really in a position to shave my whole body right now, I'm too afraid to answer those questions I'll get, but I am definitely open to shaving my ass and cock if it means less stuff getting in the way of my experiments.

I however don't know how to shave those places and am afraid to just jump in and cut my hole or something. So, I'm wondering if any of you more seasoned sissies have any tips with your experiences.

Thank you all in advance!
