My cousin sucked my dick at a similar age - but just the once. Her brother (who is the same age as me) got his dick sucked by her best friend at the same time. A well-spent afternoon, while our parents were downstairs!
To the original poster, if you used to do that and "loved it" how can you possibly say you're a straight man (honest question)
#OP Do you have difficulties understanding the concept of time?
Instead of saying "we did it until we were about 12", when you two have began it when you have been 11 years old, you could had said, "we sucked each other off three times", because that would be truthful answer.
I would understand your shitpost, if one year of your life would had something like 35 months.
#2 Because he is a fucking idiot.
