Did you ever have such an experience?(you're asking whether someone already had this experience, so it would be past tense, hence "did"' not "do") And what are your feelings about it? (How are your feelings doesn't work here, and you have to add "it" at the end to make the sentence a complete thought)
I wanted to correct it, since you're learning English. :)
As for your question, I personally haven't, but I know people who have, and I think your experience will be dependent on the safety measures that you take to protect yourself. If you plan everything out, then I think it would be fine.
