Me and my gf have an amazing relationship. So much so that even as seniors we plan to continue this relationship through college. Parents haven’t been the most supportive but it’s what we want so we’re going for it. Me and my gf have a schedule of having sex once a week in my basement , my mom allows us to hang out down there. Long story short we got caught slipping yesterday evening. She didn’t see any genitalia as we were on the chair and she started to come from behind it. She cussed us both out, yelled a lot at us disrespecting her house, and being nasty in her house and how offensive it is. She kicked my gf out and told her to walk home (she’s 10 min away not terrible). I expressed to her that we lay down a towel over her furniture, we use protection every time, and that she is looking into birth control. She is much calmer now, but i still need to talk to her about it. My mom and gf have had a great relationship up until this point and i don’t want that to be erased permanently. What do you guys think?
