Genuine Advice Needed: Advice for Losing My Anal Virginity

This has been on my mind a lot. If you haven't read any of my earlier posts, I really liking sucking cock and tasting cum. I'm debating on taking things a step further and losing my anal virginity. I think it would a super hot and intimate experience. I hear it feels really good when your prostate gets touched.

The only thing is that I've never bottomed before and if I'm being honest I'm nervous about it hurting. Is there any advice anyone can give me to make the first time as clean, pleasant and pain-free as possible? 100% I will be using condoms and I'm tested clean. Not sure how the preparation process would be, like do I just take a whole bunch of fiber or do I need magnesium citrate or is an enema better?

I'm also wondering if it's worth it to lose my anal to a guy on here, but I don't want my first time to be with a jerk.

Thanks for any help, it's much appreciated
