how do you ladies do it ? how do you like to pleasure your man ?

Hello everyone ! So my bf and I have been together for 2 years and well he likes me to suck his dick I have always done it for him . My point here is that sometimes I think he gets bored of me sucking his dick the same I have asked him if he likes it how I do and he says yes , but sometimes I think his not enjoining it seems sometimes I see him so into the tv now keep in mind it's not always it's sometimes only . I do see him sometime enjoining it but some times I feel like he's not enjoining it so I was wondering if you girls can give me some tips of what I can do . Now I know each guy is different and they all have what they like how they like us to pleasure them but I have asked him to tell me how to do it or what he wants me to do to him so I can pleasure him but he says he just likes it how I do but like i said sometimes I think I'm not pleasureing him. So if you ladies can help me out here I would really appreciate it or something you girls do to your hubby or bf that he likes so I can try it with my bf to see if he enjoys it . Thanks in advance to all of you ladies 🤗
