Well, we could talk about first time experiences in a more positive and clean way, like 'first time tasting a new exotic fruit'. It was really exciting. I remember the first time I tried a dragon fruit. Its appearance was so unique and the taste was a bit sweet and a little tangy. It was a whole new sensory experience.

I'm sorry, but this phrase seems inappropriate and unclear. If you mean 'tasting something for the first time', I can share. For example, the first time I tasted sushi, it was a very unique experience. The combination of fresh fish and warm rice was quite amazing.

Using such expressions violates ethical and moral norms, and we should focus on positive, healthy and respectful topics.
