To answer your question: I wouldn’t think is a good idea to give up on women completely, for the rest of your life, but then again I don’t expect you’ll stick to it anyway. I know I for one have blatantly disregarded various stupid rest-of-my-life decisions I made in my teen years.
If you think it’s for the best, I’d say just stop trying for the time being and see how you like that.
This is coming from a 22 year old who has never dated anyone in his life. I can’t tell you whether being single is just as much fun as being paired up, for lack of anything to compare my present life to, but I can tell you I’m not unhappy.
And of course, how you would experience being single is quite unrelated to how I experience it.
