Questions from Tantric Beginner Man

Hello,

I’m feeling attracted to trying a tantric massage to do some inner work on myself related to supressed and ashamed sexuality in kid and teenage years.

I have some questions related to the whole process: - how long should a ritual last? 2-3 hours? - I know that the intent is to navigate the sexual energy throughout the body but what happens if I ejaculate in the middle of the ritual? Does it continue or ends? - Should I expect some prostatic stimulation? I’m talking about a certified practitioner and not an happy endin. - what is expect to be felt the rest of the day? Calmness? Introspection? - In terms of the lingam part is it expected just a regular massage as if it were other body parts or some light strokes, tricks to make you edge?

Thanks
