Medical Issues

My wife has a lot of medical issues that it affect her mood, hey day to day life and our sex life. I love my wife so I refrain from asking for sex so that should doesn't feel bad but that means I only get the occasional blow job every month or every two months. Not sure what to do, just watch porn and jerk off everyday. I have an assortment of dildos that I enjoy but rarely get the chance to use them because someone is always home. I guess I am just venting and hoping my wife gets better over time and not just for the sex but so that she can have a normal life. Thanks for listening.
