I was talking to an acquaintance who attended a Journey into Manhood weekend. He was disappointed that his attractions to the same sex did not evaporate after the weekend. To be sure, he felt a greater sense of masculinity and much less self-conscious. During the first week or two after the weekend, he seemed to notice women more and did not feel the usual tug to look at gay porn. However, after awhile he noticed something unexpected. At what he felt was the height of his feelings of security about his manhood, he again experienced same-sex attractions. At that point, he began to feel an assault on his sense of manhood. In other words, instead of the sense of diminished masculinity leading to same-sex attraction, it was the other way around. His awareness of same-sex attraction came first and then his reduced sense of himself as a male.
I see no or little benefit from them on either front although some men, straight and gay, believe they have been helpful. The New Warriors Training Adventure, recommended to SSA men by Richard Cohen and Joseph Nicolosi, rarely alters SSA even though many gay males say that they feel much better about themselves as men after involvement in them.
