Unsure about my sexuality?

[IndigoBlue]

Hi, I'm a 18 years old and recently had my first experience with an escort.
The reason I went to see the escort was because I think I might be gay. I went soft in her, but I'm not sure if that was the nerves or the lack of attraction. It wasn't the first time I had sex but it was the first time I had sex with a girl.
Do you think I should play around more with girls sexually or am I definitely gay?
I honestly enjoyed the cuddling and the time spent, though.
