communication problems

Jillian
My boyfriend and I have been dating for almost a year. when we first started having sex it was my first time so I didn't know how to bring myself to orgasm or what it was supposed to feel like. One day we had sex and I used my fingers to bring myself to orgasm and it was amazing, ever since then they haven't even come close to that time I don't know if I'm trying so hard to get to that point again I can't focus on what's going on and I'm stressed. My boyfriend has only tried oral on me a few times but in all honesty he's not very good at it and I'm so nervous about trying to teach him through it that I just stay silent. now whenever we have sex it feels like he puts in little effort to get me turned on and he expects me to give him oral every time before and sometimes it hurts to have sex because I'm not even ready yet. It's become very frustrating to me and I don't look forward to sex very much. Does anyone have any tips? I'm so lost and I don't want this to end our relationship I need some advice.
