Ok, in order. You should really read a bit before posting. About one-qusrter of all women never have orgasms. Half of us do not climax from penile thrusting alone but need additional stimulation. I have been at it for a few decades and can count on one hand the number of orgasms I have had without additonal stimulation. I am typical; you are typical.
Not all positions work for all combinations. I do nto like doggy style and have found it uncomfortable with some men. With others, there is no discomfort. The size seems irrelevant but the angle and rigidity are causing pressure against your bladder in the rear entry position. Find positions that are mutually pleasureable.
Now for your g/f. There is a phenomenon known as post-orgasmic let down. It can hardly be called depression but when it is all over, we sometimes feel sad and weepy. Possibilities include that Angie is experiencing a heavy let down or she is dramatizing a bit or, and this she needs to think seriously about, guilt is setting in.
You do not mention ages for either of you. Some younger women do experience heavy guilt over being sexually active.
