The person someone is married to or living with as if married to them, or having a sexual relationship with can be called a partner:
... so (both) the partners .. should always meet the following conditions: ...
Participant is one who is taking part in an activity or event. In that sentence intimate relationships don't refer to such an activit/event.
Participator is a non-existent word, it is most likely a lexical gap.

party
3 group of people [also + plural verb British English] - a group of people who go somewhere together or do a job together
Relationships are no job, of course, but it seems logical to me to use the plural form (parties) in that sentence.
In case you don't like this alternative, you can also use partners, lovers etc.
You're making this more difficult than it needs to be. Pronouns are your friends:
