prostate stimulation

Hi. I crawled into the fetal position and inserted a finger and it felt good. at times it went up to the sphincter and the sensation was nice in that part. It was good just to lie still and just gently come hither with the finger tip. I just stimulated my nipples and i could feel a somewhat energy in my rectum and I could feel a slight pulse. I didnt want to take my finger out because i could feel a kind of energy and my prostate seemed to engorge and the whole experience was most enjoyable with precum. I tried to move my finger in and out and it was pleasant but no orgasms I am afraid apart from the one when I masturbated
