Not in the US, although I think that in some countries it is. I've had the impression - based on my travels - that they're more limited in countries like India and China. There are also social pressures in many of these countries that prevent people from accessing condoms even if there is availability.

I had a friend that started an "online condom business" which sold many different varieties and makes, and much of the business he did was outside of the US. I think it was cultural norms rather than availability constraints in most countries - but I would guess that if you're in Iran you might have some issues obtaining condoms if you are a woman (note that I have never been to Iran so this is a guess).
