Did Judas really have a Free Will?

Question:

Dear Father,

Is oral sex against the Catholic Church, in marriage of course. I feel like the Lord gave free reign but I don't want to teach this to my daughters if it is a sin. We have six(daughters). We practiced NFP, but were never taught if this was a sin. Thank you for your patience. My son-in-law just became a Catholic. He was probably to uncomfortable to ask this question in RCIA and the Question has ben posed by my daughter. You can see why I don't want to steer them wrong.

Answer:

Oral sex is allowed, only in so far as natural sexual intercourse has already taken place.

How do I define this having taken place? by having already taken place, I'm not referring to what happened last night, last week or last whenever.

God Bless,

Fr. Ray
