Homsexuality is becoming increasingly main stream in our society, and the church cannot escape dealing with it. With the recent news of a church that at the last minute cancelled a funeral of a lesbian because of discovery that a video intended to be played at the service celebrated the lesbian lifestyle.

Also, consider the excellent video series dealing with same-sex attraction by Ben Mathew in the BER Effectiveness section of the website.
