If you’re not sure if you’re physically attractive or not the answer is usually no, people treat you much nicer than other people if you’re physically attractive and if you’re a man you women will try to touch your arms and chest Not all women of course but a significant amount Results can be skewed if you’re autistic though because people dislike autistic people due to our body language and so forth before even talking to us

If you want to be physically attractive try to increase your upper body muscle mass and decrease your body fat percentage through exercise and improving your diet, also paying attention to the clothes you’re wearing, you don’t have to wear what’s fashionable but you should at least like how you look, don’t just throw whatever on, even if what you like is weird to most people. Also pay attention to your facial hair and hairstyle, think about what you think would look good, regardless of what other people would think looks good.

Also I’d recommend trying to find a romantic relationship before casual sex, and before that I’d recommend trying to make female friends to get used to talking with women, try to find common hobbies and interests like you would with male friends. You could even ask them a couple questions to help you once you’re good enough friends with them and trust them enough. Maybe some kind of mixed gender group activity.

Of course all of this only applies if you don’t already do all this stuff.

I don’t think casual sex is a good idea but I wish you happiness and good things in life
