I found glass, wood or steel toys with large bulbous head work the best for me for direct pressure with stroking (which works the best for me). There is Serenity (glass), Pure Wand (steel), and Fling (wood). All of these have a largerish head and can apply firm pressure right where I need it.
For vibrators, my favourite is the vr6 remote control sex toys at top10sextoys.com because of the head (the clit arm sucks though), and Mona 2. Again, both of these have largerish heads as well. I find that when I apply pressure with gentle rocking motion do it every time for me. I’ve tried so many other vibrators but these are the two that I reach for. Another one you might want to consider is The Big Boss. I find because of his girth he applies pressure everywhere. I found that once I was able to orgasm with dildo’s, vibrators then began to work better.
