The commissions will form Gay Week and will run in C4's morning education schedule from 26 February to 2 March.
Included in the line-up is a 5 x 30-minute series from Lambent Productions exploring life as a gay or bisexual teenager. Called Gay to Z, it will cover topics including homophobia, bisexuality and family support.
Gay Week also includes September Films' My Big Gay Prom(2 x 60 minutes), which follows a group of gay Year 11 students trying to create the UK's first gay prom and Coming Out to Class, a 60-minute programme made by Special Edition Films that follows gay rapper QBoy as he meets young gay students who have come out to teachers and classmates.
The week will also feature 60-minute documentary Gay Black Men, which follows comedian Stephen K Amos as he uses his own experiences as a black gay man to explore why homophobia still exists in his community. It is made by Maroon Productions.
Completing the line-up is Mum's Gone Gay, a 60-minute drama from Twenty Twenty exploring the life of a 16-year-old girl trying to deal with her mum coming out as a lesbian.
The shows have been ordered by C4 commissioning editor for education Deborah Ward, who said the creation of civil partnerships had had a huge impact on young gay people.
