Solo Excitement

My wife and I have been married for over 40 years. I started masturbating in my teens and continue to do so. We have never had a real active sex life so masturbation for me has been a necessity. It has been many years since my wife and I have had sex. She seems to be content to go about her everyday life not needing sex. I on the other hand have always and am still willing to have sex but having no partner I usually masturbate 3-4 times a week. I usually do it in the mornings when the wife is home. It's much more exciting knowing she is there and could pop in on me at any time. I usually rise first in the morning knowing that she will be up soon. On occasion I will start a session in the living room on the couch watching the news waiting for her to enter. The anticipation as you may suspect is extremely exciting for me. I love to masturbate in front of her but, she pretty much ignores me and does not participate in any way. She seems to get irritated by me masturbating in front of her so it's better to wait for her to get up and situated before I move to the guest room for my session. This room is next door to the living room so she can easily hear me enjoying my sessions. This is a huge turn on for me knowing that she can hear me moaning and talking. I would rather solo in front of her which is the ultimate but this will have to do for now. I have been getting louder and louder during my sessions which makes it much more exciting for me. I wish she would want to have sex or even masturbate together but I guess there just is not any interest. It seems like it would be hard not to get turned on when your husband is masturbating right next to you. I know if she was masturbating next to me I would go crazy and join in! I suspect she may also masturbate when alone but I am not quite sure. I wish I could get the courage to ask her to join me or ask if she was ever going to be interested in making love again. I guess I'm afraid what that answer may be. Maybe I will ask soon. I noticed the other day when folding laundry that she has started wearing crotchless panties. That was exciting! I am pre-cumming now just thinking about that. It excites me when I look at her knowing that her pussy is completely exposed under her pants or skirt. Maybe I should ask her about that. Maybe I could get something started? Who knows? Let's hope so. In the meantime, I guess I will settle for my solo sessions, sometimes in front of her, and the rest of the time in ear shot....I guess it's better that way than not at all!
