Why does my husband of 15 years constantly talk online to other woman?

We have a good relationship, I know he loves me, we have beautiful children, a nice home, we both run successful businesses and we rarely ever argue. We are very close as friends, and our sex life is decent for a long term busy relationship, 1/2 times weekly. Ever since I have been with him I would find him talking yo woman, these conversations were friendly but I have also found explicit photos of other woman also. I am not the jealous type, if I see an attractive woman I would point her out to him, it’s a bonus if her butt or boobs are out!

that said as we’ve got older, the amount he’s spoken to random woman has decreased, I don’t think he has the time or energy to get to know anyone these days, but it’s been the same select three almost how whole marriage. One is a female from high school he was close to before I knew him, he says she’s his best friend. They talk almost daily, the other is a woman that started off as both our friend but I no longer have much in common with her, though her and my husband have remained friendly, they talk weekly. And the final is a girl he’s never met, who lives half way across the work who he got to know a few years ago, they talk frequently. All the woman I have found explicit photos of at some point though he swears he never “asked them” to send anything. I may be excepting of friends, but cheating is not ok. I have never known him physically cheat on me, and I would leave him should I ever find that out. I was just sat here curious, like what are these woman, and why does he keep that at arms reach, why does he always need a female online to talk too?
