My goodness! Is it your understanding that the only organ of infallibility exercisable by the Church is an ex-cathedra statement by the Pope?
Now, given your running dispute with the Magisterium, I’m not sure what stock you would place in
any statement from the Magisterium, but here is one from Lumen Gentium, a product of Vatican II:
Although the individual bishops do not enjoy the prerogative of infallibility, they nevertheless proclaim Christ’s doctrine infallibly whenever, even though dispersed through the world, but still maintaining the bond of communion among themselves and with the successor of Peter, and authentically teaching matters of faith and morals, they are in agreement on one position as definitively to be held.(40) This is even more clearly verified when, gathered together in an ecumenical council, they are teachers and judges of faith and morals for the universal Church, whose definitions must be adhered to with the submission of faith.*
There are 3 organs by which infallibility is exercised. Papal ex Cathedral statements are rare - historically, arising only when an important matter of faith and morals was in dispute and needed settling.

Especially ch 3.
As explained to you many times, the doctrinal content that we are obligated to believe is more limited than the full statements that may contain them. Same sex sexual relations are morally wrong. That is doctrine. The obligation to treat everyone with respect and love is doctrine. Questions such as the etiology of SSA, whether OSA can be reignited in a person who does not experience it, the “permanence” or otherwise of SSA, whether “homosexual persons” is a good descriptor for persons with a particular experience of sexual attractions, are all unaddressed by the Church (and of no moral significance) - we are free to hold whatever opinion seems reasonable to us.
