My boyfriend is kind of small in that area?

your being a tad bit selfish expecting more uumph out of him. I've never had sex but I read stuff here and there and while I can't recommend a position, try oral and g-spot masssage those might help

1. Spooning/ Doggy-Style
2. No

no, I don't think it's selfish of you at all. I mean, don't complain to him about it because it might hurt his feelings, but you are perfectly entitled to want to get the most out of sex.
as far as positions go, I'm not 100% sure because my boyfriend and I kind of have the opposite problem, but it seems like being at a right angle to each other (as opposed to right on top of one another) allows him to go in deeper. worth a try anyhow.

Have you paid any attention at all to the many questions just like yours on this site?

Very few women get an orgasm from actual intercourse. We usually get ours from oral and manual stimulation (meaning fingering or massaging your clit during intercourse) so I don't think you have a problem to worry about.

Secondly my dear not sure why someone as young as you is having intercourse anyway!

To answer the second part YES that would be very selfish of someone to think like that.
