Some languages may use different expressions for these terms in different contexts, depending on whether whether those involved are a married couple or whether they have some other relationship. It is important to make sure that the translation of this term has the correct meaning in each context.
Depending on the context, expressions like these could be used to translate "sleep with": "lie with" or "make love to" or "be intimate with."

The term "lovemaking" could also be translated as "loving" or "intimacy." Or there may be an expression that is a natural way to translate this in the project language.
