Comparing and sexuality

So these are two separate questions

About comparing, I will always compare myself with others of course and it is devastating for me to see people who are better than me.Like today I saw a guy I knew at gym.He is much bigger than me and I feel bad and small and he is big and better and I am worse I failed.Why do I have to bother comparing myself and try to feel more than an usually ending up feeling less than.How is your relationship with this part?

And about sexuality, I am craving for being intimate with someone it excites me too much and I will be in search for this when I feel down and empty. I want sex or sexting with someone,felt desired,see someone naked,masturbate in order to feed this part. I don’t even think it’s horniness but is longing for someone closeness I guess.Yet still wants that arousal.Do you experience this and how are you doing with it?
