Wow, I was also raised by a single mother and also have two systers just like you, but my mother pushed for sexual freedom bullshit thus my systers are completely fucked up and childless with no possibility to ever having a family, I am often told by ppl who know me and my family that I was the only one who came out right. Having to deal with my mother and my systers has taught me the power of telling women NO and pissing them off.
Sexual freedom reduces reproduction.
Interesting how advanced societies adopt this and then die out.
