P waves

What do p waves feal like? I have heard so much about them. Are they different for everybody? Tonight I felt an on and off kind of vibration feeling coming from my prostrate area. It didn’t go all through my body just part of it. It was kind of a large area too kind of from my prostrate almost up to my stomach area that big.
