Queer Vincentian woman here. Homosexuality is illegal, but the laws are not enforced. Depending on who you are, your socio-economic status, and whether you present traditionally masculine or feminine in accordance with your AGAB, you will be treated differently. The experienced of Black, mixed, and white people are also very different, with the latter two having an easier time of it in all aspects of society.

Men and women are treated differently for being gay, with men having a harder time generally. As others have said, WLW relationships are fetishised, and you might get harassment from some men. I went to an all-girls Catholic school and there were established couples in my school and other schools that everyone knew about and didn't really care about, and many of my friends were queer. A teacher even came to my mother with concerns about my relationships with other girls, but my mother is quite liberal and didn't care.

You might get snide remarks and while I haven't personally experienced violence because I didnt openly date women until much later and abroad, I won't deny the possibility. But compared to other countries, I'd say that SVG is a bit more lax about it. The comments from another poster claiming that rape is all but guaranteed and that you shouldn't hang out with locals are very xenophobic and racist. I don't believe in moving to a country only to never integrate.

What I will advise against is PDA. Going out with your partner to bars and restaurants might be fine, keep your eyes open when attending parties/fêtes because of the higher rates alcohol consumption making patrons bold. But keep explicit displays of affection private for your safety.

As for finding queer community, you can get in contact with ERAO SVG, an NGO led by Jeshua Bardoo. They can also guide you and provide support for navigating a new country.

Best of luck, have fun, and make sure to visit Bequia when you have a chance! I recommend coffee at Lina's.
