Not sure what you are looking for. Buenos Aires has many gay venues, and there are obviously lots of gay people here, both foreign and native born. I don't see guys walking around arm in arm or any same-sex public affection on the streets, but of course, kissing is universal and the nice thing is you can kiss your friends, straight, gay, male or female without anyone blinking an eye (that is on the cheek). Will you be accepted here if you are gay? How "accepted" would you be if you are openly gay in NY, SF, London or any other large city? There are people who will be fine with it and people who will have problems, just like anywhere else. I think if you are a gay man who has lived anywhere, you have learned how to be discreet when need be, and you know how to find your own kind (I am gay by the way). My response to your question would be that you won't have any problems as long as you act intelligently, are discreet, and don't expect some kind of gay paradise, because I don't think any exist (I live in SF by the way, and it is by no means gay paradise).There are many sites where you can get information on gay venues in Buenos Aires. Just do a search for Gay Buenos Aires. I think you'll have a good time here.
but some of my dear friends in Bs As are.
