Sex w my mans

So when me and my bf have sex (I’m a pretty awkward gal) I like dont know what to do? I don’t have much sexual experience but we’ve been having sex a lot but he likes to do most the stuff during so I’m still kinda like not sure what I should do. Like i feel awkward having my eyes open and I dont know how I can also contribute.. and sometimes I’ll get on top but I feel like he doesn’t feel it as much as I do and I dont know how to really please him while on top either. How do I not be awkward and how can I be sexy and how can I please him more??? Advice and tips are needed! Please and thank you!!
