I've seen quite a bit of research that suggests a high correlation between men ejaculating and protection from prostate cancer. In the study (Australian I believe) men who ejaculated (in any form) more than 21 times a month had the lowest rates of cancer.
This has changed my attitude, despite being open about sex etc. I used to see solo play as a bit shameful and not something to spend time on. My wife works away three days a week at the moment, so the only way to up my game is some solo time while she's away.
I've been keeping track, and it's quite a high number, only managed once recently :-) I'm lucky in that if she's not in the mood, my wife will always give me a hand if she's here.
I just wondered what other people thought? Both sides of the equation really - what do the partners think of their men knocking one out for health reasons? And men does it change your attitude?
