Having trouble deciding a country to visit

So I've been debating for about a month and having issues choosing a place to go for my first far trip as a solo male. I've been to Colombia and the DR that's all.

I can stay a month or two whenever I go but also think of going to 2 different places but not sure as that takes a lot of planning.

My problem is that I'm currently trying to learn Spanish, although I'm inconsistent but want to be more consistent and going to a Spanish country to immerse myself will be helpful. Plus I love latina (and black) women, so would love to date or even find someone where I can have a conversation with them and make myself learn Spanish lol. Just fyi, dating good women, not into prostitutes.

That being said I don't want to go back to Colombia or the DR again (I love those places but want to try something different, latin America and Mexico is close to the USA. I'm trying to do my first trip far away. I heard Spain isn't great for African Americans. I'm trying to wait on Brazil since I'm in Spanish mode and trying to learn that. Not sure what to do.

I'm open to going to other places and thought about South Africa, Nigeria, Kenya, Thailand, and China. I really want to go to South Africa but I heard there are safety issues and not being able to go out at night, which is kind of lame not to be able to go on vacation. I'm not a night life person and don't drink so maybe I'll be fine but I heard even in the day it could be dangerous. Granted I heard these same things about medellín and I went and had no issues.

Thailand is high on my list, although I would go for dating as I'm not into Asians much but I hear they are even racist towards darker skinned people. Seems like there is something wrong with every place lol. I know as a traveler no place is going to be perfect and I will feel out of place in some form or fashion but I'm trying to make a decision in the next few days.

I want to keep it cheap or moderate just because this will be my first time traveling far, not sure if I'll like the place, the food etc. so I'm going to save the more expensive trips for when I'm well seasoned. 😄

I'm 42 male (be 43 in about 3 weeks) African American from Texas. I only know English at the moment with some basic Spanish knowledge.

Any recommendations?
