Do you mean publicly or privately? Publicly, sure it has increased. Most people won't admit to something that they'll be shamed for. Privately, how could we know? Has there always been more or less the same amount of gay sex going on behind closed doors regardless of the situation in the public sphere? My default assumption would have to be yes, unless I saw compelling evidence to the contrary.
I think it's pretty safe to say that people will act less on something if they feel it's bad (due to being educated like it is), even behind closed doors. Especially since this makes it harder to find a partner.
I read a statistic once that said the high water mark of homosexual relationships in the United States was during the Second World War (because all the men were overseas together and all the women were back home together). But you don’t see that portrayed in media.
