Has this ever happened to you? TMI

My so and I are ttc and obviously have been having unprotected sex. So after sex I was just lying in bed looking up recipes ho hum. And when I went to get up, his sperm literally ran down my legs! In all the years we've had sex without a condom I've never had it run from my lady bits clear down to the floor lol! Has this happened to you before? Is it common? I'm not concerned just wondering if anyone else has experienced this 😅.
