Help, why can't i have feelings for this guy

He is loving, nice, we share same interests, we like almost the same things, he makes me feel confident, he makes sure i'm feeling okay, makes certain sacrifices for me, tells me the truth, he makes me feel safe. He is everything i'm looking for in a boy. Here is my problem: 1) I don't find him attractive looks-wise, so sex won't be good, kissing won't feel natural, i think only holding hands and hugging would be compatible, but i'm a sexual person so sex is a big thing if we are going to have a relationship. 2) i want him in my life , so sorta using him emotionally because i like the way it makes me feel. 3) He asked me out in April, but i made an excuse on how corona was damaging and i needed space and stuff (but in reality i found him physically repulsive). Lately he has been giving signals, possibly going to ask me out again. Now i have think of an excuse , and would probably leave me because he would think why give her time when she doesn't want to take things further.

Any advice?

Also the reasons why i don't find him attractive:
Although he is slightly taller than me, i kind of a want a height difference , Also his hairstyle and his style it's self. Also he sorta gets bullied and doesn't have confidence
