Pretty sure this person asking for people to share their experiences of cuckolding/hotwifing isn’t actually a woman thinking of trying it.
Suspect it might be a specific poster who has been repeatedly banned before (also posts under different names about certain clothing items, certain body types, questions about whether people had sex on Valentines Day or have ever shagged a flatmate and - weirdly - police raids).
