Not enough sex

My cycle recently ended and my sex drive has just sky rocketed. Lately I've been asking my boyfriend for sex or trying to drop hints, but he's either busy with homework and projects, or it's the wrong place at the wrong time and I have to wait until later.

There's nothing wrong with that, except I don't feel satisfied. I want him to be rough, but that means loud sex and we share an apartment with other people. I don't want to be THAT couple you know?

And.. he also finishes before I do. All the time. He offers to give me oral because that's how I usually get off during sex, but lately I just don't want oral. I don't want him to touch me the same way he always does. I feel a little deprived and upset, because the last few times we had sex I haven't came. I want to bring it up to him, but I know he has had a complex about not being good enough in bed for me and I don't want to hurt his feelings. Granted he hasn't spoken about it since we first started dating three years ago, but I feel as if those ideas are still deep down inside of him.

Any advice? On having sex or maybe just talking about it with him? I just feel a little scared about it.
