I encountered another gay story line of a Portuguese Soap Opera on YouTube. Of course soap operas aren’t reflection of life but… The Soap opera is «A Herdeira». The story deals with the tribulations of gay parents, infidelity and closets.
The person who posted it is Sean O’Shea – https://www.youtube.com/channel/UCgkShoZZuuGj4PQQU8KcA_Q
The story line is of Dinis e Salvador.
Portugal is quite progressive and tolerant, isn’t it! This should be a neat event!

Olà. I acknowledge that this thread is 2 years old, but I just came across it, and I thought I’d contribute. We were just in the Algarve this past winter, where we bought a residence (Eastern Algarve). We are not in the habit of doing PDA in our home country (Canada) and did not do any while in Portugal, although it was likely obvious that we are a couple. We had no issues per se. On the hand, we tried to find networks of / for gay people in the Eastern Algarve, without success. There is a bar in Faro, but it appears tailored at younger folks (it opens very late, well after our bedtime). We did not find any LGBT venues or networks in Tavira, where we are settling. The services and business people we have been dealing with for the purchase of our residence in Portugal have been very nonchalant about our being a gay couple in their dealings with us. Essentially, our experience has been neutral, which implicitly makes it a positive one (i.e. no concerns).
