I am 28 and I value the Holy Sacrament of marriage. Sometimes I dream about a future life with my wife (no face) and kids. Sometimes the thoughts are slightly sexual. Is it morally wrong?
These thoughts sound normal, provided you are not encouraging them or fantasizing about them. Have you undergone any form of vocational discernment? If not, you really should because we (as humans) don’t always know what God is calling us to do.
Yes, but not mortal, I would say, if they are not dwelled upon, deliberately created or used in order to achieve arousal. When such thoughts arise, try to bat them away with a prayer.
