You have mentioned how vibrators could make a women desensitized over time with clitoral orgasms, and you have recommended women with male partners to choose dildos with diameter sizes the same size or smaller than their partner. I have been using your diet, and believe that I have been getting more vaginal sensations after using the gyneflex. I did seem to have my first vaginal orgasm after the first time I used the most firm gyneflex setting. Since then, using this setting feels more like exercise rather than pleasure like the above as the firmest setting seems to get more flexible with more use. I was considering buying a dildo made from a hard substance such as silicone or glass, but I'm concerned that it could interfere with my sex experiences/exploration with my partner (we are both healthy and in our mid-late thirties). Any thoughts?
