"Asexuals" are just a different strain of Chadsexual. Having sex is one of the most important things to do in order to bond as a pair, and the studies that show how foids' likelihood of cheating increases with number of partners and how they compare every later fuck to their first one proves that.
Sex is supposed to happen between two virgins who bond for life. Not saying it's realistic to expect that in today's soyciety, but it goes to show how important sex is for a functioning relationship and having some sort of deeper connection with your partner. If your partner isn't willing to have sex with you, then you'll never have that deeper connection, and at that point you have to ask yourself "what is my value to this person?" "Is there really anything deeper going on here, or is this just a platonic friendship with a different label?"
And again, obviously my answer is an ideal and in no way realistic or achievable for normies, and especially for any of us. I'm just saying, don't get into a "relationship" without sex, and be surprised when the foid goes and runs behind your back and suddenly "finds her sexuality" with a Chad.
