Small town casual dating?

I'm new to casual dating in general but now living in a small town. There's only so many activities in town. What is the deal if you have two lovers at the same event?

My current FWB I know has other partners (yes we're having safe sex) so I know for a fact we're not in an exclusive situation.

However there's a new guy that I'm into that seems more affectionate in public. All we've done is kiss so far but can I get some advice from other people that have lived this life?

Thanks.

Also no slut shaming or religious-asshole talk. I was monogamously married for seven years and healed from my divorce for two years before considering dating and that marriage was miserable okay? Go somewhere else if you wanna shame for sex because I don't care about your opinion.
