I had sex for the first time on sunday, and its now tuesday. whenever i wipe there's a pink tint on the tissue....sometimes it looks a lil red. is there a reason for this?

Postcoital bleeding: Needs checking with a doctor exam and a smear if not uptodate. Depends on your age. If younger you may have cervical ectropion but do need checks to exclude medical conditions that may be serious

Normal: The hymen is a donut shaped tissue at the entrance of the vagina. It is torn normally with first intercourse. The bleeding should not last more than a few days.
