Think I experienced Pwaves, but cant get further

Had a 3 hour session with the helix last night, where i went from ‘do nothing’ to gentle contractions, occasionally stoking my nipples & smoking weed.

if i really concentrate, i get into a mode where my heartbeat gets fast and so does my breathing. it feels like it’s building to something, but i cant really get over the edge.

Has anyone experienced this and have some tips to share? is this actually a p-wave?

i got about 5 build-ups in the space of 3 hours. they felt really good!!
