You are 100% correct, I have bought the mornign after and i felt like i was shamed as well. It is so sad that in this day and age that we have to be made to feel that sex is bad.
When i first traveling one of the first things i noticed is that there are condoms in the checkout isle with the candy! so easy!
I am not sure about the morning after or if they have it, but it is easy to go to a pharmacy and buy almost anythign you need in most countries and its not a big deal. In the US i feel we are shamed for soooo much! especially when it comes to sex related topics.
