M25 straight introvert but I enjoy anal play

I don't know anyone to talk about this in real life or online and don't want to do it never used a meeting app but I don't feel safe about those things

Last night I was playing with my dildo but thought that doing it alone was monotone boring and started fantasizes about doing it with a stranger because I'm too shy to talk to a person I know.

I thought about doing a well warm up and stretching for my asshole, then plug myself and find a street hooker In a distant city and ask her to just use the dildo to fuck my ass, I know it's a weird request to do even to a prostitute, and I'm worried about getting hurted(internally) by her I haven't done anything with anyone or outside my house and idon't know if I will do this in future but the idea doesn't leave me
