Don't know about the 10 stages before sex, but I found this rivetting piece of information on one of those 'new age/spiritual awareness'-type websites. It's expressed in hetero terms but feel free to gayify it

The 12 Stages to Angelic Intercourse
Stage 1: Ordinary - Any Part A Into Any Hole B: At this level, both the man and the woman are only seeking to gratify their mutual lust and discharge their accumulated desires for sex - anyone will do.
Stage 2: Ordinary - A Particular Part A Into A Particular Hole B: At this level, the man and the woman prefer to be with one another. They start to become partners and do not want "just anyone". The energy begins to arc back and forth in a line between the man's penis and the woman's vagina.
Stage 3: Ordinary - Simple Pathway of Desire for Partner A and B: At this level, the desire starting in the man's brain travels through his heart before reaching his penis while the woman creates a path of desire from her heart to her vagina. The energy travels in a flat, thin "U" shape between them during sex.
Stage 4: Ordinary - Complex Pathway of Desire for Partner A and B: At this level, desire starting in the man's brain goes through his Heart, Solar Plexus, and Sacrum before going to his Root/Penis. The woman creates a path of desire going through her Heart, Solar Plexus, and Sacrum before going to her Root/ Vagina. The energy travels in a short, thick "U" shape between them during sex.
Stage 5: Ordinary - Advanced Pathway of Desire for Partner A and B: At this level, the desire starts in the man's Crown, going into his brain, travelling through all his Chakras, and out through his penis. His energy is received into the woman's vagina, joining her energy, travelling through all her Chakras, and out through her head. The energy travels in a tall "U" shape between them during sex.
Stage 6: Ordinary - Circular Pathway of Desire for Partner A and B: At this level, the desire starts in the man's Crown, going into his brain, travels through all his Chakras, and out through his penis. His energy is received into the woman's vagina, joining her energy, travels through all her Chakras, and out through her head. The energy becomes his then hers as it flows between them. The energy flows from her head back into his forming a thin, circular "O" path between them.
Stage 7: Angelic - Connected Pathway of Desire for Partner A and B: At this level, the circular pathway between the man and woman becomes a fusing and a merging of their energy. The energy flowing between them is his and hers and both. The energy forms a thick, circular "O" shaped path between them which runs in a continuous circle through their Chakras during their lovemaking.
Stage 8: Angelic - Connected Pathway of "Personality" Chakras for Partner A and B: At this level, the circular pathway between man and woman is so strong that it pushes out into their Personality Chakras. The Personality Chakras are the lower three: Root, Sacrum, and Solar Plexus. During sex, they become linked together in that order - the Root first, the Sacrum next, and the Solar Plexus last. The energy flows in a thick, circular "O" shaped path and also in straight lines directly between the Personality Chakras of both individuals. Energetically the bottom half of the "O" has three lines running through it.
Stage 9: Angelic - Connected Pathway of "Spiritual" Chakras for Partner A and B: At this level, the circular pathway between man and woman is so strong it pushes beyond the Personality Chakras out into the Spirituality Chakras. The Spirituality Chakras are the next three: Heart, Throat, and Third Eye. During sex, they become linked together in that order - the Heart first, the Throat next, and the Third Eye last - after the Personalities have connected. The energy flows in a thick, circular "O" shaped path and also in straight lines directly between the Personality and the Spirituality Chakras of both individuals. Energetically the "O" has six lines running through it with space at the top.
Stage 10: Angelic - Completely Linked Chakras for Partner A and B: At this level, the circular pathway between man and woman is so strong it pushes beyond the Spirituality Chakras into the Crown Chakra. The energy flows in a thick, circular "O" shaped path and in straight lines directly between the Chakras individuals. Energetically the "O" has seven very thick lines running through it.
Stage 11: Angelic - Completely Connected Chakras for Partner A and B: At this level, the Chakras of both individuals are completely fused together. There is no his and her energy: there is only us. The energy flows harmoniously in all directions. Energetically the "O" is completely filled in with energy.
Stage 12: Angelic - Completely Connected Energy for Partner A and B: At this level, the Chakras of both individuals are so strongly fused together that is pushes out into the Inner Energy Bodies of both individuals - literally, the two become one - the ultimate fulfillment of the bond of love. The energy flows everywhere instantaneously. Energetically the completely filled "O" keeps on expanding outward until both partners are fully linked at all levels.
