It took me way more than 6mo to get my first BBS shave, and once I got it I stopped worrying about it. BBS is always nice but as many have already said, each shave is it's own experience. Each shave I try to get better at technique and improve the shave experience and results but I'm comming up on a year now and I still don't get consistent BBS, although I am getting comfortable shaves on a regular basis.

Granted you wanted advice on shave results and all I have to offer is a simple suggestion. I used to run my hand up and down my face immediately after the shave to check my results. In time I realized that my face hairs are still swollen with water immediately after the shave so the results I was feeling were inaccurate. Instead, try checking your results an hour after the shave and see how it feels. For me the results always seem better after my face has fully dried.
