When your twin sends love or thinks about you intensely, you can feel it in your body. Your lips feel weird because telepathic kisses work by one twin visualizing what they want the other to feel through touch. When it comes to the pleasure feeling - even when far away you can feel aroused or experience pleasure from your twin because there’s an open telepathic channel that’s physical too, not just emotional. Random sensual feelings out of nowhere are often your twin reaching out. Often a strong sign they’re thinking of you sexually.
So yeah you got kisses and chakra activation going on together. The pressure plus pleasure thing makes sense.
