New to the “bull” side of things how do I get started respectfully?

Hey everyone, I’m a 26M, confident, clean, and in good shape. I’ve had a fair amount of dating experience (body count 8+), but I’ve never stepped into the “bull” role before. Lately I’ve realized I’m genuinely attracted to older women, MILFs and married women and I’m curious about navigating that world responsibly.

For those who’ve been in this dynamic: • How does someone new get started? • What’s the best way to approach couples or women respectfully and ethically? • Any do’s/don’ts to avoid rookie mistakes? • Where do people usually connect specific communities, apps, or subreddits?

I’m not looking for anything messy or disrespectful just trying to learn, stay safe, and approach this in a mature, consensual way.

Thanks in advance for any insights.
