This is what's kept me so drastically confused over the years, because I'm a very tactile person. I'm naturally affectionate to friends, and flirty with sexually attractive strangers. I'm confident and I come on strong. I have sex with 90% of my friends. Sex is a norm in my friendship model just as a side effect of the type of people I hang around with. Hanging out with a friend typically looks like: get coffees, talk and joke around, watch Netflix, have sex, cuddle, talk some more. The key difference is that all of those actions are me and the other person expressing friendship and sexuality, not romantic feelings. This becomes extra complicated when I'm especially close to that friend, such as being invited to their family functions. When somebody has a crush on me and I become aware of it, it makes me extremely uncomfortable. Instead of the casual sex and light-hearted joking, they'll suddenly be shyer. They'll start going out of their way to TRY and please me with gifts. They'll ask to kiss me during moments that aren't sexual, which is the big red flag. If this starts happening, I stop having sex with them. Most people take the hint at that point. If they don't, I'm straightforward and usually have to end the friendship. Blessedly this doesn't happen very often. Being a highly sexual person has definitely made it harder for me to realize my aromanticism, but once I took notice of the lines I won't cross-- It clicked. There ARE lines, but they're probably different for everyone, and vary from culture to culture.
