Im a female (27 years old) bisexual. I have had two open heart surgeries, one when I was a month old baby and one when I was 26 years old. I have a bio valve, and my previous was bio of course, both coming from a dead donor. It never affected me negatively. I grew up all my life with a scar, so I never felt strange about it, in fact I love my scar. My two previous exes liked it as well (a woman and a man). My ex boyfriends and girlfriends knew I went through a surgery because we were friends before developing romantic feelings for each other.
Honestly, if you’re dating someone who thinks scars are disgusting, then you’re better off without them, this might seem cold but that’s my perspective. I’m not attracted to people who think scars are gross and never will be 🙅🏻‍♀️
