Is it normal i can't feel very turned on unless i have a deep connection?

This is also a concern for me because I have noticed I have to really either find them attractive emotionally and psychically in order to be aroused or be in love with them, to feel turned on. I also need to trust them 100% and I can't trust people when people are ever so fickle and change from one moment to the next.
I had some strong feelings for someone once, many moons ago and for thr life of me couldn't get them out of my head.
I dont know how ill ever feel truly turned on? I find the body kind of dirty and grotty and can only have sex with someone clean who takes pride in their appearance and washes regularly as well as bein in love.
I can't make myself fall in love and I am worried I won't ever find someone who is my type and vice versa whks clean and that I fall in love and therefore want to go all the way sexaully.
