We say love is important in marriage but given the importance of finance and intercourse, it is important to ask questions before you get in.

Discuss what he does and how much he earns. No, not just "I work at XYZ bank", get a detailed reply " I work at XYZ bank as a marketer employed full time, I earn XYZ amount after tax. However, I have this other income from XYZ investment" (as it applies to him).
Of course this needs to be discussed in a mature way so you don't look like you are only about his money but hey, it is what it is and his financial profile is important (yes, from a religious and secular point of view)

Ask about his sexual orientation and history and add this to the findings from your own private investigation of him (what, you think he can't lie or 'forget to mention'?).
It's marriage and it is intended to last forever, why take chances not finding out?

**********************************************
Having said that, please know that he will be asking about your sexual orientation, sexual history and financial profile as well, if these are important to him (And yes, you'd need to give detailed answers too).#copied
