Today i had an unusual but enjoyable experience. I am booked in the hospital to have Botox injected in to my bladder. I have an overactive bladder. A Nurse aged i guess in her mid 30s. Was teaching me to self catheterize. She was nice looking. She had a lovely way of talking to me. She demonstrated how to do it. I was naked from the waist down. She was holding my Penis and inserting the Catheter. I didn’t get a full erection. But i was semi hard. I was enjoying feeling her hand on my penis. She inserted the Cather and urine drained from me in to a sterile jug. She was still holding me when she was slowly withdrawing the Catheter. All the time she was talking to me. When she had done it she asked me if i was happy with the demonstration. I asked her if i could try for myself. She prepared a new Catheter. I was struggling to find the hole. I have a back problem and it was making me lean backwards. She held my penis and helped to guide it in. I am sure that if she had been moving her hand it could have given me an orgasm. When i was going for the appointment. I was reluctant. I was thinking of making an excuse for cancelling it. My wife told me i had to go. After my experience today. I would go any time.
