Could have something to do with it but not the main reasons.If loss of sex drive is an issue for you and or your partner it could be due to low testosterone which begins to decline in men every year after about the age of 40. If thhat's the problem then there are prescription strength treatments a doctor can give (for really bad cases) ooor if it's just normal loss of testosterone there are a number of over the counter options to boost testosterone Like the one you see retired football players promoting all the time on TV. Not only can they help with a declining or dead sex drive but it can also help boost your energy levels and improve results from working out to keep up your muscle mass. The one promoted on TV is from GNC and is kind of expensive but there are also two or three plant based supplements that are supposed to boost testorterone and they tend to be less expensive
