Newly single sex questions

So I’m newly single - I’d been with the same man for 17 years and now I’m starting over. I’ve met a few guys already and want to sleep with them but I’m not sure how this works...

1) is sleeping with them on the first or second date bad?

2) i enjoy giving head, should I do it to these new guys? With condoms, without???

3) I also like anal... should I wait for anal until it’s more serious or does that even matter?

4) I had one guy ask to pee INSIDE me!!!! (We haven’t even had sex yet, we were just talking about it) when in the hell did that become a thing?!?!

PLEASE HELP
