[MF] engaging with a sibling

I know in todays society this is something that comes across very wrong and judgmental but are there other people out there that have or currently are involved in a sexual way with a sibling? I (M 20) Currently am involved with my Sister (F 18) and as someone who’s experienced this it’s definitely a different type of bond for sure. It’s a privacy thing with us as our father who has since passed two years ago, and our mother were always very strict and super religious growing up. Our mom has zero idea about us and we keep it that way because she literally no doubt, would kick us out if she knew. It’s been a struggle and has been honestly awkward at times but we’re adults and accept it for what it is. We started gradually and eventually got to the point where we are at now. Honestly just curious if there’s others out there who have or still currently in “relationships” with their own sibling and how they go about the process?
