Nope, your pedantry is no help at all.
I expect Pope Francis knew what he  was doing when he gave his document the title "Amoris Laetitiae" and that translating that into English as 'The Joy of Love' is appropriate. It does suggest that just maybe 'Love' – especially married love – can be joyful!

If you want to reduce all love to sodomy, that is your mind at work. It is not in the words Francis uses.

Though I would suppose all genital activity is pleasurable, or people would not engage in it.
