I'm like the only one in our system that experiences sexual attraction so imma try explain:
Basically, sexual attraction is seeing someone and um... wanting to do it with them. When looking at someone ur sexually attracted to, u blush and get kinda nervous, and think about the possibility of doing intimate things with them.
Aesthetic attraction is looking at someone and thinking they're cool, pretty, cute etc. but just wanting to look at them, and not considering being intimate with them
Hope this helps :)
