Most of what is known about his Gnostics if from their detractors, like Epiphanius, Bishop of Salamis.

4:4 And the husband will move away from his wife and tell her�speaking to his own wife!�'Get up, perform the Agape22 with the brother.' And when the wretched couple has made love�and I am truly ashamed to mention the vile things they do, for as the holy apostle says, 'It is a shame even to speak' of what goes on among them. Still, I should not be ashamed to say what they are not ashamed to do, to arouse horror by every means in those who hear what obscenities they are prepared to perform.
4:5 For after having made love with the passion of fornication in addition, to lift their blasphemy up to heaven, the woman and man receive the man's emission on their own hands. And they stand with their eyes raised heavenward but the filth on their hands and pray, if you please�
4:6 the ones they call Stratiotics and Gnostics�and offer that stuff on their hands to the true Father of all,23 and say, 'We offer thee this gift, the body of Christ.'
4:7 And then they eat it24 partaking of their own dirt, and say, 'This is the body of Christ; and this is the Pascha, because of which our bodies suffer and are compelled to acknowledge the passion of Christ.'
4:8 And so with the woman's emission when she happens to be having her period�they likewise take the unclean menstrual blood they gather from her, and eat it in common. And 'This,' they say, 'is the blood of Christ.'
5:1 And so, when they read, 'I saw a tree bearing twelve manner of fruits every year, and he said unto me, 'This is the tree of life,' ' in apocryphal writings,25 they interpret this allegorically of the menstrual flux.
5:2 But although they have sex with each other they renounce procreation.26 It is for enjoyment, not procreation, that they eagerly pursue seduction, since the devil is mocking people like these, and making fun of the creature fashioned by God.
5:3 They come to climax but absorb the seeds of their dirt, not by implanting them for procreation, but by eating the dirty stuff themselves.
17:4 For I happened on this sect myself, beloved, and was actually taught these things in person, out of the mouths of people who really undertook them. Not only did women under this delusion offer me this line of talk, and divulge this sort of thing to me. With impudent boldness moreover, they even tried to seduce me themselves�like that murderous, villainous Egyptian wife of the chief cook�because they wanted me in my youth.
17:7 (For whichever is prettier flaunts herself as bait, so that they claim to 'save'�instead of destroying�the victims of their deceit through her. And then the plain one gets blamed by the more attractive ones, and they say, 'I'm an elect vessel and can save the suckers96 but you couldn't!')
19:3 For the nature of such a viper is similar to the wickedness of these people. In performing their filthy act either with men or with women they forbear insemination, rendering impossible the procreation God has given his creatures�as the apostle says, 'receiving in themselves the recompense of their error which was meet
When I first read the key excerpts in Meditations on the Tarot, known to have been written by Valentine Tomberg, 25 years ago, I at once noted how similar this is to Tantric Practices.
