Heard hear! I say that as the former younger partner in a gay relationship that featured a 20-year age gap. Later I was the older partner in a relationship with a much smaller but still significant age gap.
The funny thing is that in both relationships, the age gap was not in any way negative to US. In the second one, it wasn't even something we noticed.
But other people sure did!
I guess it's human nature to judge and gossip, and sometimes the gossip isn't really ill intended, but it would sure be nice if people could extend "love is love" to happy couples with an age gap.
