Since extreme workout, Constant urination.?

Well, The other day I participated in Outdoor Paintball with a group of friends. I haven't had much exercise before this and now I cant stop urinating. This all started on this day. I go several times a day and a few times at night... doesn't keep me up but wakes me up. That day I felt great and to today i feel great i feel energized and more alive... if that makes sense... lol.. What can be causing my constant urination?
