How to sneak in/out of house to have sex?

So I'm an adult who wAnts sex and I might move back into parents house (( due to a psycho roommate )) my mom and step dad are very religious and if they had even the slightest suspicion I was having sex that's the end of my life. I work nights but they basically know I come home around 8-10 pm the problem is if I come home in the wee hours of 1-2am they'll know something's up and I just don't know how to get away with it. Also i get dressed and makeup in the bathroom , so if I have a date then she'll know I'm seeing a guy and she'll know if I come home super late that I was having sex.
Honestly I don't know what to do I can't find another apartment due to certain financial reasons
I guess I could schedule my dates in the day time but what's the fun in that lol
