Based on our experience, please find below a few questions to be asked.
Are you both willing to do what you plan to do?
If one of the partners is passive or not interested the experience will be less interesting.
What are your rules, your limits ?
Those can be really different depending on each one. Sometimes so different that the compatibility will be low.
What is your mid term goal ?
Do you want to have a one night stand, or are you happy to even spend a week end together if there is a match ?
