Both my boyfriend and I are relative novices (i.e each others firsts), but we're looking at trying different positions apart from missionary and cowgirl. I'd really love for him to make love to me from behind as I've heard you can achieve deeper penetration. In any case we've tried it a few times and he just can't get it in. Are there any special angles that we are supposed to be sitting at in order to achieve it? Mind you his taller than me. I think he might be getting a little put off trying again and again only for it to fail.
