may I be so bold to say that the OP at age 64 is probably having an ED problem?
I am 57 and my BP meds lessened my erection quality, so I got a pump, and some Viagra. I pump 2 brief sessions a day, and jelq afterwards. this results in me having a nice plump flaccid cock,(not distorted) a nice bulge in my pants all day long. one day my wife noticed my bulge, fondled it and to the bedroom we went. popped a 50 mg Viagra, and foreplay began, got a massive erection, you know the rest. my pumping seems to help me "jump" start a good chub, and Viagra does the rest.
I also do some kegels, and since I have been using the pump, my EQ has gotten better. I think making your cock stand at attention a few minutes a day improves the blood flow. some morning wood are at almost full rock hard now, and I have fucked the wife a few times or she has jacked me off while I had my morning wood. and I am not sure about this, but I seem to be longer when I take the Viagra, and don't know if it is the pump or the Viagra. I am using a 2x9 cylinder, and I fill the cylinder with my girth totally, and any "pull" from the pump is exerted on my length. I don't really want to get bigger, I have trouble "filling" the currrent size tool, without making it bigger. I am 7.25 x 6.25, at the base close to 6.75". my wife told me years ago, "please don't get any wider. it feels good, but at the limit." but if I got to 8" in length I would just keep taking the viagra to achieve that size.
we have all heard "variety is the spice of life", and I am not condoning infidelity, but I have noticed, if flirting, say in a bar situation, that I get pretty turned on by an attractive woman, much like I did in my 20's. I achieve a nice chub. so I sometimes wonder if I was single and could change my sex partner from time to time if I would not need any "wood" meds.
