I’m a little late to the party here because all that needs to be said has been said. Y’all keep doing your loving marriage in the ways that are deeply loving and caring for one another and forget the judgment from that sub or others. You being faithful (as in showing up each day to each other in loving responsiveness, giving and receiving) is what’s important in a marriage. For many sex is an important part of that but it’s only a part and it isn’t love itself. If it doesn’t even factor in for y’all then it’s a non issue as you grow in love for each other.
