On the Sex Talk FAQ, there are threads on zinc and on increasing your load, and one on enhancing female orgasms which contains some good links to webpages with nutritional info on male as well as female arousal.
There are also lots of webpages out there on naturally increasing testosterone, but most of the googled pages are ads for particular supplements, so although the info is often good, you are somewhat on your own ferreting out the wheat from the chaff.
