Am I headed in the right direction?

I tried the Selle Diva Gel Flow Lady and it was comfy on my sit bones, but put pressure on my girl bits. Currently trying the Specialized Lithia and it is fairly comfy. Good on my girl bits and sit bones, but it seems to rub where my thigh meets by butt on the left side. The right side is fine. I must sit crooked on the saddle or something.

I'm thinking I need a 155mm (I was measured) with the same cut-out as he Lithia, but more T-shaped? Does that sound right? What would you recommend? Is the Jett the best saddle to try next?

The Jett is pretty much the identical shape as the Lithia, only firmer.

Not sure about the Ruby.

I'm on a Jett right now, and it's acceptable, but my next try is going to be a $elle Italia Turbomatic. I don't know for sure whether that's more T-shaped than a Jett, but it appears from the pictures that it is. If that one doesn't work for me, I have no idea what's next.
