That’s part of how I found out. I had suspicions cause of trauma but I feel like it was confirmed after I had sex with someone I felt safe with. I just don’t feel sexual attracted to anyone. The one time I did it was mainly just the physical affection part. I’ve never felt the need to take it further and I’ve never understood how it’s a “need” for so many people. I think I assumed I wasn’t ace at first cause I knew I was romantically attracted to men.
