Dating pool is murky

I’ve put myself out there after a tumultuous divorce. After licking my wounds for a while I’m ready to date. I’ve made profiles on a few dating sites. Are all guys the same? I even put on my profile I’m not looking for hookups. The number of unsolicited messages and pictures I’ve received is unreal. I was texting one guy who was halfway decent and respectful. Told him I was working and he replies “I’m naked at home and need you to work this”. After days of talking normally. Why are they like this? I’m 36 and have looked around my age if that helps it make sense any. Another guys asked me how I was doing and when I replied I was doing well he answered “Do you wanna get fingered?” UGH. Just venting I guess. Where are all the respectful people
