Love. Relationships with no love and just sex are…“friends with benefits”. Relationships with love and no sex is “marriage counseling” lol. Love would matter more because if you love someone a lot you will work through it until there is sex. If it’s just sex though, then you can just dump the person and move on to someone who wants both. Love, and also love yourself (loving yourself helps you find someone decent, not loving yourself can lead to you dating people who use/abuse you). Sex can either be fun for a while on it’s own or painful…where-as sex with love is the best thing ever. So love :) It compliments everything in your life if you find it :)
