Is it normal to have these sexual feelings

100% it is. A ring on your finger doesn't make you super or non-human. Having feelings like that after being married will happen. You are in fact a terrible person if you do not control it though and let those lusty feelings make you do things that you can't as a married person. Let me restate that - if you in any way act on them while being married you are terrible - having sexual feelings or thoughts towards others after marriage 100% normal.

yes, that's totally normal, you wouldn't be human if you didn't

You would be abnormal if you didn't.

good question? depends on the mood.I have always had a burried artsy fartsy side and now as i get older i want it out sometimes.maybe i get too carried away

what are you...man or woman? Lets revise that...is it usual for a married man to have sexual cravings for another man?

Think it is, but to what extent is the question. However, marriage is ment to strengthen the bond between you so it would be wise to try to hold on to that.
From a biological perspective it isn't the easiest not to have these feelings since a huge part of us is driven by lust.
