Alena ,

Maybe I do not understand the translation of your post correctly.But I read that you liked the conversation with that man.

And I am not sure if you 2 have already met each other.Was your communication on Skype or other video chat ?

You say that you don't feel comfortable to go on a vacation , when he is making certain insinuations or proposals.

Personally , I Always go by this rule.The man should come first to the woman's city/country to meet her.
And it is only after this , that you 2 can make a more or less good estimation , if you 2 are compatible.

Only talking through media or telephone or Skype , will not tell how a person really is.

And when a man comes to visit you , it is a sign of respect and of interest in you as a woman.
Asking you to go with him on a vacation , is one thing.Did he give you a solid proof , that he had all the tickets and arrangements for this trip ??

How can you tell if this is all true ??

Let him come to you , and then show you the hotel bookings , plane tickets etc.
Then you will know for sure.

Also asking you about your private areas , is to me a big red flag!
So , think about it and ask yourself , do I really trust him ?

Going on a wild adventure may look appealing.But it is also a wild risk.

Take a deep breathe , let it of your mind and look for someone more suitable.

Good luck

Eric
