Acts?  If it's about the mechanics, Jay, intimacy will not be optimally loving and loving will not be optimally intimate. I'll assume that you, like I am, are a long-married heterosexual person. So I gotta ask: what drives you to even care for one nanosecond about how your consensual  neighbors make love, from foreplay to act? Do you have access to a Syllabus of Intimacy Errors or to a how-to manual or do you, as a caring, compatible lover, instinctively, with your partner, "know." If my question is intrusive, consider how it must feel for those whose confession of intimacy sins is demanded by you. Let's both listen to our mothers and mind our own business. And let's both re-read Orwell about what happens when people claim a right to opine on, demand confession for, and judge (indeed expect punishment for) the private lives of others.
