What are some credible resourses for learning and training in the art of Tantra?

I have never been interested in such arts until just recently…I have fallen in love…we have not yet made love, but both have expressed the need to do so in a highly spiritual manor…

have never trained in the arts of Tantra

I know my body well enough to realize that I have problems with controlling or rather properly guiding my flow of energy, this manifests as premature ejaculation followed by flaccidness of the phallus

this woman is also inexperienced with guiding her energy, this manifests in her in the lack of orgasm

we can not afford expensive seminars and classes from Tantric Masters, and prefer to practice on our own any how

what are some good sources of information, literature, videos etc

that we can begin training with

Thank you all for this great community and resource
