It stands out when couples don't know how to talk to each other, whether it was that way when they were growing up, or a mistrust to open up. All the assumption can be eliminated just by honestly communicating with each other, especially when the problem is sexual in nature, and one partner will not open up to the other. It doesn't matter if this guy is gay or not, just the fact she doesn't know for sure is the problem. No communication, no relationship.
