Quickbeam,
First, congratulations on your gains.
Here are my recommendations.
Don’t worry about PE for now. If you must do something then just do a little maintenance. At 6.5x5.5 inches you are well into the above average crowd. Your dick size is more than enough to please 99% of the women out there. You can break up your maintenance routine. 5-10 minutes in the morning. Piss pulls during the day. Another 5-10 minutes at night.
Get back in college asap. Try getting into a local community or Junior college and get your associates degree. Most junior/community colleges are much cheaper than universities and that coupled with living at home cuts costs way down. Then get into a state university, they are cheaper than out of state or private schools. If there is one in the local area all the better. You can stay at home and finish school saving more money while you are doing it. Apply for grants, loans, scholarships, etc. Bottom line if you have the ability to do well in college, then get back into it now. I doesn’t get easier the older you get.
Sorry, but while you are in your parents home you will need to abide by their rules. If you get where you can’t stand it, move out, but understand it gets hard out there trying to finish school at a minimum wage job. It is possible, just harder and usually takes longer.
Bottom line: you need to figure out what is most important to you now and in the long run. Set your goals accordingly and work like hell to get them.
Take care and I hope you reach your goals.
