Ok guys, here's my situation.  41 year old male, maybe 10-15 pounds overweight, definitely out of shape though (couldn't run a mile to save my life!).  Average looks (there's a reason I'm mentioning this).  

I've noticed that a few times over the last few months, I started to lose my wood towards the end of a session.  One time I couldn't get it up at all.  I think it's partly mental - I'm an average looking guy and I know these girls wouldn't be with me if it wasn't p4p, and I think about it during the session.  However, I don't think that's the whole cause - I definitely need to stop being a couch potato.

I decided to try Viagra and it sure did the trick lol.  50mg, empty stomach, 3 or 4 or 5 drinks lol, and it was hard as a rock.  BUT, the feeling was not good at all.  It was like I couldn't really feel much.  I've heard some experience that some don't.  

My question is, those of you who have experienced loss of sensation, have you switched to either Levitra or Cialis, and did you experience less of a loss of feeling??

Thanks guys!!

Lose the weight and exercise instead.  I dropped 50 lbs over the last year(50more to go) and started walking/running 3 miles a day and wood is not a problem now.  Will turn 60 in July.  Do yourself a favor and get off the couch

But exercise makes me horny as hell.  I sometimes get a half mast while riding my bike....no lie.

Instead of drinking try skipping the booze and taking 25mg of Viagra.  It may be all you need and the numbness may be lessened or eliminated.  The key to Viagra is not to take any more than you need.

to answer your question, all three ED drugs can cause decrease in sensation as well as making it more difficult to cum. I do believe that vitamin V is the worst offender.

The extra weight has a physiological effect on your performance, as well as a mental one. When I was carrying a lot of extra weight, I found that my own body was a turn-off for me. I would joke with women that she had to be sexy enough for both of us, but in truth I experienced that sensation of "not being good enough".

Don't drink alcohol if you are using ED drugs. Also, try a smaller (25mg) dose of V - if you don't have real ED, then you are just looking for a boost and 25 is all you need, and the side effects will be less.

And I call bullshit that you can't walk a mile. I bet you can. If not, walk a half mile and work your way up slowly. You'll thank us, and your dick will thank us.

Guys, thanks for the advice!  I'm REALLY going to make an effort to lose these last 15 pounds and get back to the gym.  I have the time, so there really is no excuse.  

I may try 25mg of V in the meantime, just for a little kick, and to ensure the flagpole doesn't go down at the wrong moment lol...

Eat better..lose meat and dairy and your hardness and resistance  will improve

If you can't run, start with walking a couple of miles.  That and cleaning up your diet will make a huge difference.  I lost 20 lbs, and not only did my libido improve but stamina and enjoyment as well.  It was difficult getting started, but now I look forward to my daily exercise and feel bad if I don't make it for some reason.  Also, sent PM about your choice of supplements.

the Viagra instructions ae to use the smallest dose that works.  My MD prescribes the largest pill (since they cost about the same) & instructs you to get a pill cutter.  The coating is because they taste aweful...  what I imagine sh*t would taste like (never tried it, TYVM).  Cut pills go down fine with a glass of water.
There is at least one study, I can't find the link now, with men with PE.  Viaga doubled the time to E.  Unknown if it acts the same in men with ED.  The presumption is that it does.  ED is about blood flow.  ED can be an indicator or Heart problems.  Being as cardiac fit as possible is a plus.  
The brain is an important part of sexual response...  losing your focus is pretty much the kiss of death for erection...  at least for me.  I take pains to structure the environment to help not hinder focus.  (No distractions, music soft enough that it doesn't intrude, TV off, no outside noises, no rushed schedule creeping in)

And there are plenty of good looking gals out running and biking on the same paths I frequent.
