Help! Why do I get so wet during sex?

Melissa
In the beginning with my partner it was only sometimes I would get dripping wet. Then I became sexually active (2 years ago) and only just recently, during sex I get extremely wet (all the time, whereas before it was only sometimes it would be that bad). So wet that he points it out and has a hard time finishing, same as myself. Is there something wrong with me? Or am I just so turned on that this happens? I am on Trisprintec birth control as well and have been for quite a few months. Please let me know what you think!!
