You sound like you're expecting instant results and it doesn't work like that. A very few have been fortunate enough to feel a "super-o" on their first session, but the majority of us have to work at it.
I suggest you read through the sticky posts at the top of this forum, especially "B's Keys to the Backdoor" and "B's Best of the BEE-Line". Lots of good advice in there.
The main things you should concentrate on are becoming comfortable with the Aneros being inserted, and breathing slowly and deeply. Don't have any expectations, just let whatever happen and enjoy it.
I would also suggest longer sessions, 10-15 minutes is really on the short side, perhaps 45-60 minutes would be better. In the end, each session seems to get better, so give it a chance to work its magic, don't expect something to happen, but rather enjoy the sensations you feel as your prostate begins to awaken.
