Catching your partner having sex with someone else can be turned into a huge dilemma. But catching your own parents having sex ...that's a nightmare that could leave you scarred for life. Here are some tips to handle a situation where you walk into your parents' "time".
Cope with hearing it. You could drown out the sounds by strapping pillows to your head, blast some music through headphones, or use ear plugs. However, you can also make them aware of the "floating" noises being heard around the house. Try scream the lyrics of a song, for example, "Let's Talk About Sex" by Salt n' Peppa. You could also march up and down the hallway yelling, "Who's the Daddy" or "Who's YOUR Daddy".
Act innocent if you accidentally walk in on them. Even if they're cuddling without clothes on, you wouldn't know when is the right time to enter or not. You can either do one of the two following actions:
Strike up a normal conversation, trying your very hardest to not show any emotions or feelings. Be prepared for any defense excuses they may give you; you'll have to choke and swallow it for the time being.
Blackmail them. Grab a camera and take a photo. Suggest that if they ever behave in such a way again, the photo may end it at a work place, email inboxes, etc. Hide the keys to any handcuffs or steal any potential "tapes". If you fail any of these, just try out and weird them.
