I have never done any sound play or catheters as a sub but have done catheters has a dom. It sounds like it can be a lot of fun.
JenSchaefer,
It can be extremely fun if done gently and sensibly while respecting your and others boundaries.The following is a generalization based on my experiences that you may find helpful,having been a dom, you probably know some of the things below. I have done U S(urethral stimulation) on myself since my early teens,with women only after I was living on my own.
With men, it causes delightful erotic sexual stimulation, passing through the prostate is not always a must. With women, there is often a companion/similar experience, being that women and men have the same nerve endings in the genital area.
1) In all cases, for the beginner, sounds and catheters need to be slightly smaller than your urethra.
2) In all cases, sounds and catheters need to be well lubricated (with a sterile lubricant to prevent UTI,urinary tract infection and tearing of tissue) before insertion.
3) In all cases, sounds or other devices that are to be inserted and then re-used must be aseptic (cleaned and then washed with alcohol) to prevent UTI (urinary tract infection).
4) In all cases, catheters must be sterile (sealed sterile package) and then disposed of after use,to prevent UTI (urinary tract infection), period.
5) In all cases, hands & fingernails must be clean, in situations involving partners, gloves are strongly suggested to prevent UTI (urinary tract infection).
6) In all cases and circumstances be gentle, if it hurts..stop..something is not right, period.
It is my hope that you will find some thing in these thoughts that will lead you to another aspect of delightful eroticism.
