An expat lesbian here once told me about dating porteña lesbians. She said that they are just as nuts as the straight ones are. Possessive, insanely jealous, everything you have heard before. Of course there are exceptions, or there wouldn´t be so many people happily coupled up on this forum, but those are hard to find. Dating here is rough no matter your sexual orientation! A porteño is a porteño is a porteño, no matter whom they choose to have sex with. Also, once the women hit about 26 they start to severely stress about settling down, so if you´re a guy or a lesbian reading this who has been with an Argentine girl over 25 for at least 6 months, get ready for her to bring up marriage soon. Yes, you bet I am generalizing, but you see and hear these stories so often it´s hard not to.
On a side note, OP, sorry to hear you´re seeing an Argentine therapist. They´re a joke and a waste of your time. They give no constructive advice and do not help you to create coping mechanisms. They just sit there and nod, and then say that psycho/depressive behavior is a normal expression of emotions, because there is nothing more unhealthy than keeping your emotions inside. I went to one, and gave up after one session because she told me that rather than try to solve any problems here, I should just go back to my home country because that's where my family is. I told her that I had many of the same problems even there, but she just shrugged and suggested I look for flights. This woman was in Recoleta and came highly recommended. What a waste of 200 pesos. (This was before I got health insurance). My boyfriend has been seeing and Argentine psychologist for more than a year. This supposedly great doctor one day asked him where to find flores (the "good" weed here). My boyfriend doesn't smoke, it was just a question out of the blue. I flipped shit when he told me this, because he´s really been struggling with some family stuff and this stupid doctor basically just chats with him once a week, and then one day asks him for drugs.
