You know the old maxim "It is better to keep your mouth shut and be thought a fool than to open your mouth and prove it?" Lies. Learning doesn't occur when you don't ask questions.
You should take this as a learning experience, PUNCH. Being a part of the fitness world means someone's going to be giving you grief about what you're doing no matter what it is. Even those (rare few) who are legitimately trying to help. If you want to succeed, don't worriy about what other people think you should be doing or even what they think of you and do pay attention to the useful information they're offering and look at how it may help you meet your goals.
What I'm trying to say is that just because a bunch of guys have made posts in this thread implying you're a lowlife because you asked a question then used the replies you were given to adjust your program in a moderate fashion so as to gauge the effects of the change doesn't mean you have to do exactly what they tell you to do, or become upset over some of the comments. Progress in your training will come from knowing your body and challenging it as best you can with the knowledge you currently have. There was nothing wrong with your question and your initial response to the replies.
Having said that, allow me to fill in what I think any reasonably knowledgeable forum member could tell you:
You're most likely doing way too many reps. Low intensity, high repetition workouts increase muscular endurance. If your goal is to add muscle mass (hypertrophy) then you need to do higher intensity workouts with lower repetitions (volume). This means doing (for example) 3 sets of 10 reps, going to fatigue (defined here as the inability to lift the weight again using proper form) on each set. Increase the weight when you can do more than that amount of sets for reps. Feel free to experiment to see what works best for you. You may find yourself doing 5-6 sets of an exercise as you become advanced in your training, 3 sets is just a guideline for beginners.
