I agree it doesn't take that much longer but there is only so many hours in a day. In my view, why submit to an extra 60+ TGPs that only offer you a category of 'Gay' to submit to?
Its like targeting the keyword 'sex' in search engines... it's far too broad and you simply will not convert. So why submit a micro-niche gay gallery to such a broad term like 'gay'. The numbers you would have to have to make a sale would be huge. I would rather use that submitting time to do other stuff that always seems to build up throughout the day.
