leaking after intercourse

I have been sexually active for a little over a year with my husband. I was a virgin when we got married, so I admit that I don't have much sexual experience. But I have a question about leaking after sex... before I got married I knew that sperm leaking out after sex was something to expect, and that a lot of people even keep little towels or things handy so to not leak all over the bed. However throughout my whole marriage I have never noticed any leaking... I go to the restroom afterwards and I clean myself up, but I never feel like anything is going to pour out of me... Is that normal? Is it something I should be concerned about?
