Genesis — 18 God said, “It is not good for man to be alone”. [...] 24 For this cause a man shall leave his father and his mother, and shall cleave to his wife [...]
I am a Protestant (partially because of this disagreement with Catholicism). I do not think God intended men — even priests — to be alone.
And, while I think the “celibacy leads to pedophilia” charge is WAY overblown — I think there may be something to the thought that priestly celibacy tends to lead men with homosexual tendencies into the priesthood.
If a faithful Christian man were struggling with attraction to his own gender, the priesthood is a good place to go where his marital status, lack of dating and/ or sexuality will likely not be questioned. This is obviously not universally the case — but I would bet the percentage of priests with homosexual urges exceeds the percentage of the general male population with homosexual urges.

That's not a problem with celibacy per se, but with the Church's failure to properly vet candidates.
