Coming from a research background, I hate assignments like this because there is no point to them. Everyone will give you data that is incorrect and will not help you in either proving or disproving your hypothesis. Regardless of whether it's informal or not.
Anyway, I'll chime in:
Male, 26, around 90 minutes per month... estimating that each text takes about 1 minute of my time.
RE: the insult "That's gayer than AIDS"
Your insult would have made sense if it was said in the 80s or 90s, but now the incidence of AIDS is more prevalent in heterosexual individuals*... the correct way to try pwning someone with that statement now a days is to say "I'm sorry to those I offend, but that was officially more heterosexual than AIDS".
