How many can you marry? Can a man have more than one wife?
No, it is written Matthew 7:12; "So whatever you wish that others would do to you, do also to them, for this is the Law and the Prophets", this means if you can not be jealous of your wife kissing another man, then she can not be jealous of you having sex with another woman. Surely if you found the right woman, she is enough and you don't need more? 1 Corinthians 7:2; "But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.".
A woman would get jealous of you having more than one wife unless she was bi-sexual which is sin: Romans 1:26; "For this reason God gave them up to dishonourable passions. For their women exchanged natural relations for those that are contrary to nature".
It is adultery having more partners than your spouse.
1 Timothy 3:2 and 3:12.
