Lack of Affection

My boyfriend got upset yesterday and spewed out all these feelings about how he feels like the effort isn’t the same from me as the beginning and how he has to beg for affection. He said that he doesn’t only want to be intimate while we’re having sex. I feel like I can 100% be more affectionate, it’s just hard because I’m not an affectionate person and I literally told him this when we first met.. it was amongst our first conversations. He told me “I can change that” lol but here we are and it’s an issue because it hasn’t really changed. I don’t know how to be affectionate and I feel like I try but his affectionate can come off as smothering so I’ll eventually tell him to relax. I love him a lot, I’m very attractive to him in every aspect .. I just don’t know how to show it other than sex. Theres not too much of a backstory on why I’m not affectionate besides I didn’t grow up in an affectionate household. I just wanna know has anybody dealt with this? I want to be affectionate and make him feel good outside of sex as well but I don’t wanna force it because I’ll cringe lol
