Straight men want to try something with a man

Hey so I'm M21 and I always wanted to try something with a man. I'm not attracted to man but I would like to try some new things (blowjob , anal , kissing a men ). I've never put anything in my ass,

do you have some advice on how to find a man willing to do that? ( Like on a website/irl ?).

How can I prepare for all that ? And maybe some other things that I might need to know.
