April Masini is Ask April, founder of Relationship Advice Forum, this is especially true when couples haven’t lived together (with a romantic partner) before, notes April Masini, New York-based relationship and etiquette expert and author. “They expect that what they know to be true in the relationship, will continue.” But the reality is that living together can throw a wrench in the middle of what used to get each of you revved up.“ Seeing a partner naked all the time, using the bathroom and losing the sense of urgency that dating can foster with sex, can dampen your sex life and dash your expectations,” Masini explains. “When couples have a more seasoned view of sex over the long term, they’re less disappointed when their sex lives ebb and flow when they live together.”
