Well if the Gnostic gospels are to be believed, the reason it probably seems like there was homosexual overtones is because Mary Magdalenes true role was suppressed by people who then edited the bible...it becomes clear that it was likely Mary Magdalene who Jesus had a relationship with... The bible was changed and the womans role was revised in a demeaning manner (she was portrayed as a prostitute) in order to fill whatever agenda at the time. When you leave Mary out of the picture, of course Jesus seems likely to be gay.. but with the missing information we can conclude that originally he was portrayed as having a woman companion..
Excerpt from Wikipedia, Gnostic Gospels...
Mary Magdalene
The Gospel of Philip has been cited for the idea that Jesus married Mary Magdalene[2] Much of the Gospel of Philip is dedicated to a discussion of marriage as a sacred mystery, and two passages directly refer to Mary Magdalene and her close relationship with Jesus:
There were three who always walked with the Lord: Mary, his mother, and her sister, and Magdalene, the one who was called his companion. His sister and his mother and his companion were each a Mary.
That passage is also interesting for its mention of Jesus's sister (Jesus's sisters are also mentioned in the New Testament at Mark 6:3), although the text is confusing on that point: she appears to be described first as the Virgin Mary's sister, then as the sister of Jesus, although this may be a translation problem. The other passage referring to Mary Magdalene is incomplete due to damage to the original manuscript. Several words are missing. The best guesses as to what they were are shown below in brackets. Most notably there is a hole in the manuscript after the phrase "and used to kiss her often on her...." But the passage appears to describe Jesus kissing Magdalene and using a parable to explain to the disciples why he loved her more than he loved them:
And the companion of [the savior was] Mary Magdalene. [Christ loved] her more than [all] the disciples, [and used to] kiss her [often] on her [mouth? face? cheek? head?]. The rest of [the disciples were offended by it and expressed disapproval]. They said to him "Why do you love her more than all of us?" The Savior answered and said to them, "Why do I not love you like her? When a blind man and one who sees are both together in darkness, they are no different from one another. When the light comes, then he who sees will see the light, and he who is blind will remain in darkness."
