I've never been in that situation but distractions causes me to loose focus & go soft.  A ED drug might help but only if you use your mind to focus on the lady you are with.

I've taken the 50mg V and it did little to help.  My doc just gave me 100mg but I haven't had a chance to try that strength yet.

Hope it works for ya.  I share your frustration.

On the contrary, the atmosphere was so sexually charged that I was hard all evening. I went with a FAV of mine from the hobby and it was amazing. Although surrounded by other couples and threesomes "going at it", we didn't play with anyone else. I was surprisingly not embarrassed or reticent to be viewed by others.  In fact, I was more erect and for longer than I generally am with even the best provider that I have been with. for me it worked!

They work by allowing your blood circulation to increase, thus allowing for the physical possibility of an erection when the mind  deems it proper.

Since you know your plumbing works, they won't be doing anything further to advance that.

You clearly have a mental hangup about being in a room with more cock present, a situation I also share.

So, rather than take a strong medicine, instead just limit your sexual experiences to women and let that be your vehicle for sexual satisfaction?

Viagra to get over a limp problem that occurs when the condom comes out. It was definitely a mental thing, but using the V definitely helps.

Viagra and such are vascular dilators and do nothing for your mental state. Men with ED have performance anxiety on top of a physical defect. It's a shame some providers latched onto Leno's 4 hr joke.
