What's going on ? TMI

Okay so when me and my SO have sex of course there is discharge from his sperm to my cum . I clean myself all up and we go to bed , I wake up once in the middle of the night to more discharge which is normal to me . I clean up again and im out for the rest of the night . Recently , for the past two days everything is the same but this time I've been waking up 3-4 times in the middle of the night to the wetness down there . This morning when I woke up my underwear were drenched , from front to back . What can be going on ? There is a smell but its the smell of his sperm , no other funky smell. I showered and I literally have to wear a panty liner so my underwear dont get wet ? What could this be ???
