This is bad for a host of different reasons.  One-do you really trust someone you don't know to sell you the little blue pill? Second- (not judging here) but if financially you are in a spot without insurance or the ability for a Physician visit maybe hobbying isn't for you right know. Third-There are numerous online Pharmacies (with just a few questions) will supply Viagra/Cialis etc in small quantities. I know this from actually a friend (Woman-who we have not been intimate)  does this to keep a supply on hand for her liaisons, she is a bit of a Cougar but does claim to give it to younger dates to make sure they have "Stamina"-her words not mine.

Are you asking us to practice medecin without a license, Mr. LEO?  
Are you willing to assume the risks of taking medication without being properly evaluated?  
How will you know that blue pill is safe?  
Is it what I say it is?  

Play safe. Go to a clinic.
 

It is expensive but once you own one you will never need an ED drug again.  Takes some practice getting to know how to use it.  It will keep you hard no matter what!

I have heard from my clients that Vitals is like $50.00 a month and is better than viagra and others say it doesnt work. So all I can say is try it.....

iagra will help if you have ED - not sure anxiety is something it treats - maybe you need Xanax or simillar. Or maybe start off your sessions with a drink or two.

Viagra is dangerous if you are being treated for a heart condition with nitroglycerin tablets or a patch or the like. The interaction can be deadly, due to a s serious drop in blood pressure. However, if you're having chest pains when going up stairs, shoveling snow, or whacking off, you should be seeing a cardiologist.

Simple Solution

Cut the root out, rather than hacking away at the symptomatic branches. That is to say, work on your nervousness, rather than ingesting a pill that may or may not work for your situation (and have who knows what side effects with your unique physiology), when any troubles over "hoisting the mast" are nothing more than a symptom of the anxiety.

My suggestion: do some alpha brainwave exercises. Les Fehmi is an excellent resource, having researched this area for decades. His website is http://www.openfocus.com/

Awesome side benefits of moving out of the anxiety/fight or flight state include an ability to connect with the world more deeply, a better ability to be in the present moment, enhanced sensory experiences (including such physical experiences you might be hoping to enjoy on your dates), and increased creativity (I can only imagine where you might take that on a date! ), among others.

Second, find ladies who are known for their ability to really focus on making a connection and being attentive enough to know what needs to be done to get there. In your case, that may be a lady who is willing to take it slow, doesn't have her personal ego wrapped around your performance (as if it's some extension of her own) and has the capacity to get you out of your own head. I would also recommend making the investment in something longer than whatever your current average date length is. It clearly isn't working for you, and it may be wise to invest a little more time with a lady new to you so that you can establish your own level of comfort.

Finally, you're not alone. (And honestly, I think this is something that a lot of guys need to hear.) A lot, and I mean A LOT of gentlemen experience nervousness and anxiety. And really, that is ok. Your only job in these encounters is to find a space to enjoy yourself, and the fabulous thing is that that can mean whatever you want it to mean. You have the power to put the priority/spotlight on whatever you want to on a date. Perhaps shifting the spotlight a bit to focus on other aspects of the connection, and drawing your hyper focus away from the thing that brings you most anxiety, might be precisely what the Doctor ordered.  

You don't need no stinking Viagra.

If you get hard outside of meeting providers then it isnt a physical thing...its mental.  
The hobby is supposed to be a enjoyable relaxing experience...If you need that type of crutch you should really ask yourself is it really worth it?

My advise is go with a well established provider in order to get rid of the wonder factor, explain your anxiety, and meet up.  Maybe have a drink or 2 before hand to calm the nerves (if you drink of course, and dont get blitzed)

Also I agree with the others when it comes to you making a wrong move by asking for medication on a forum. Its harmful on so many levels to be asking something like that... for you and for the person whos stupid enough to give it to you without knowing your medical history.  

good luck
