Hi all! I hope I posted this in the right place, I'm new to the site. So, I'm wondering if anyone can give me info (personal experience, links to scientific studies, etc) on how effective the diaphragm is sans spermicide? I've been using the diaphragm on and off for a few years with great success but recently the experience of using spermicide has become akin to douching with sandpaper - and the effects can last days. Fun times! My partner hates condoms, and I despise hormones, so I'd *really* like to stick with this method...just without nasty chemicals. I know there are more natural spermicides in other countries, but sadly the U.S. likes to ruin women's sex lives, so that's not an option for me either. Any advice or input is greatly appreciated. Gracias!
