It has been ages since I've needed to use a condom, but now that I am hobbying, it is a necessary evil.  However, nothing kills my erection faster.

I don't think I have ED, everything works just fine during uncovered activity.  But within seconds of putting one on, I go limp.  
 
So, my questions are: does anyone have any advice or suggestions in dealing with this?   My doctor suggested I'd try a female condom.  I've noticed some providers advertise as "female condom friendly."  But it is really a big deal to inquire if a provider is willing to use one?  From a provider POV, is using a female condom an issue?  Is this even a good solution?  Is it just a matter of getting used to wearing the Trojan again?
 
Everything works just fine during uncovered activity, but despite the best efforts of some wonderful women, condoms just seem to leave me hanging.

Is the FC2 the answer?  Does anyone have any other suggestions?
 
Of course, I could just stick to multiple BJ per session

my guess is that you anticipate the lack od sensation, which is negligible with modern condoms. You need to discipline your self to maintain your erection. But to increase sensation I've found that applying lube to my penis before application helps.

Trojan Supra
Crown Skinless Skin
Kimono Micro-Thin (come in Large size too)
Durex Sensi-Thin
Okamoto 0.02 (mm) Hydro Polyurethane .... there are some other good options also but having i'm having a brain fart now.  

Utilizing cock rings (especially vibrating ones) are fun too.

Wait until it cools down below 90 degrees. Also drink plenty of water. Depending on your age this heat has a way of taking your energy away, impacting your ability to get/maintain and erection.

Working with toys, such as a cockring might help... Also, you could try training yourself with a condom. You could bring yourself really close and then put a condom on before you finish. Or just stop sex and masturbating for awhile and eventually you'll readjust...

I sometimes have the same problem. What I have found is that the combination of a cock ring and female condom works well. Just tried the combo last week and had a great long session.
And, I finally found an adult store in the DMV area that carries them. Don't want to shill for them on the board, but if you PM me, I will give you the name of the establishment.
Finally, P411 list of activities can include FC2 friendly, so would try one of those ladies first - she probably has them and has some experience with them. I know several ladies in DMV are FC2 friendly.
