You need to get new friends. You are the average of 5 people you
hang out the most with. What you are doing now is just a temporary
band aid for your deeper problem and that is the lack of intimacy
with females. You are trying to compensate that need by going to
KTV. Does this make you feel good? I guess you are asking alot of
questions here but you know what you do is against your own
values.
Get a new hobbie, go out more, talk to people, put yourself out
there. Make new connections. That is what you should be doing
instead of going to KTV. It feels good now but in the long run it
will do you more damage than good.
