Is this a bad sign?

I've been chatting with this man on bumble for a few days. I've been enjoying his sense of humor. We been talking about possibly meet casually at a coffee shop and then he sends me a picture of his torso showing his boner under his sweat pants. Ugh. Is this normal or just normal behavior for someone who only wants to have sex? I dated a guy for 2 months and he was sending similar pictures AFTER our first date but before our first date, which I didn't appreciate but I didn't want anything serious at that time. That situantionship didn't end well and looking back it didn't start well.

I might save this guys'd info in case I want casual sex lol BUT I was hoping to find a LTR-material man. Would such person behave the same way? Or just those who want to have sex? Not sure what to expect anymore.

The men on bumble are either too slow/messaging too many women or too forward like this. tinder is a joke in my area and an app I go to get a few laughs.

ETA: I unmatched him. It took several minutes for things to sink in. I guess unfortunately all my short experience after my divorce has been with men who only want to have sex. Sigh. So I guess this has become my normal.
