I hate how nothing I do turns my boyfriend on

I could wear short shorts, sexy top, no top, full makeup, whatever... he will sometimes stare at my body but he won’t get hard or want to have sex. I try to kiss him on the neck all sexy or gently play with his hair and he always gets mad and swats my hand away and says I don’t know how to play with hair. 🙄 He won’t show me how he likes it either. I try rubbing his junk and he pushes my hand away and gets irritated. I try whispering in his ear “I need you tonight” and he’ll get irritated and say I’m too tired. The way he reacts just embarrasses me and he doesn’t care.

He only wants sex when HE wants it. As in I can’t get him in the mood myself. It makes me so annoyed and feel unattractive even though I know I’m not at all. Like he watches porn and obviously gets turned on by those women but not me? I don’t try to turn him on most of the time because I know I will be turned down. Even when I try to send sexy texts to him when we’re not with each other he gets mad.

I know 100% he’s not cheating.

But idk what to do about this? We’ve been together over 3 years and this has been an ongoing thing for a long time.
