Should my boyfriend and I work towards partnered orgasms, when mutual masturbation is working for us so far? And if so, how?

I am a 19 year old woman in a relationship with my awesome boyfriend. We are pretty much satisfied in our sex life, mostly because of all the cuddles and love. There is a question that I have, though. Usually we go at it (and do many types of sex) for a couple of hours, and then when we are ready to finish things, we both touch ourselves until we climax....

I don't want to give a guy oral sex...but maybe I do?

I come here quite often to browse and get information I need, and now I need some advice. Since I was 13 and started dating and getting more intimate I decided I didn't want to go down on a guy. I had quite a few reasons for it and on top of it I just found it abnormal. Well now I'm 15 and have been in a relationship for quite some time now....
