Tha,
I have suffered from the effects of asthma and I just wanted to let you know that it can be triggered by stress. While I do not believe your BDSM activities caused the attack, asthma does drain all the energy out of a person. I am glad to see you care about your partner and are considering all possible causes that could trigger his attacks. I am also glad he is seeking help from a psychologist. I too suffered from abuse so I have been wondering if it will affect my journey into BDSM. I wish you both well on your voyage and want to thank you for your post. It really does help me to hear how others are doing in their BDSM life style.
