I also happen to have a low libido that makes me basically asexual. I have never had sex nor do I particularly have the need or desire to. I believe I see sex in a different way than most people do and this may be influenced by my lack of sex drive. — darthbarracuda
So you have a low libido, have never had sex, and feel asexual. I sort of feel that way myself, now that I am fairly old. You should live your life the way you see fit. Since you have not, and maybe will not experience sex in the manner that most people do, you might want to be cautious about which interpretation of sex you adopt.
Sex as mere biology (though nothing is "mere", per Feynman) limits our understanding of sexuality as much as presuming sex to be a patriarchal subordination of women or a capitalist transaction or thinking that men defile women during sex.
The ways we are embodied and the way we experience the world are closely tied up together. It is through our body (including sex) that we experience the world and it is within the body that we build our being. If we can't comfortably exist as the body we are, we can't comfortably exist in the world [except by maintaining very carefully policed non-porous boundaries between the self and the world].
Sex seems clumsy, awkward and particularly unsanitary. — darthbarracuda
Life is unsanitary. We are surrounded by an ocean of biological particles, viruses, bacteria, pollen, parasites, dirt, odors, and so on. We inhale and exhale, eat and excrete all sorts of creatures and biological by-products. We are constantly shedding skin; there is an army of skin-mites in your carpet, sheets, mattress, and pillows eating and digesting your skin. We lose our skin about 12 times a year. The skin mites and other scavengers that live with you are grateful for your flaking hide. There are more single celled creatures inside of and on us (and you) than there are bodily cells. Gut bacteria in the trillions aren't just there, they are absolutely essential. Animals evolved together with gut bacteria. We can not do without them.
Young children who are not exposed to enough bacteria, viruses, pollen, dirt, and so forth tend to get sick more often and have very strong allergic reactions and asthma because they missed getting dirty enough. Once you are grown up, playing in the dirt ceases to be beneficial to the immune system.
Sometimes sex is clumsy and awkward. How else can it be in a small car, in a tree, in a public washroom, in the snow, in the sand, in the choir loft, etc. Older, wiser, and better funded people arrange for a bed, bath, and beyond -- like privacy, the right temperature, food and drink, etc.
