Yeah I'm the same way - can only O from clitoral stimulation. Either masturbating or receiving oral. Which rarely happens anymore...

One time - and one time only - I did O from intercourse that got my G spot. But I have not been able to duplicate that since.

And I've noticed, since I started Zoloft, that I can no longer get there from masturbating. I don't know about anything else yet...my husband hasn't touched me since I started the Zoloft over a month ago...
