Hello: I Have Been Using MUSE Placed Into My Urethra.

Hello: I have been using MUSE placed into my urethra. My wife reports that her lips have become quite swollen after keeping my penis in her mouth and she is starting to get a "gagging" sensation in her throat. She is an excellent partner and we are worried that she might develop swelling of her windpipe or throat, also. This has not occurred yet. Is it O.K. to continue? Thank you, H. Keim
