Not everyone can or should be sexually active. However, if you want to find a wife (and believe me, you want someone you can cherish for life, not a mere depository of bodily fluids), you need to start going to places. You must have a friend who is more socially active than you, and if you don't have one now you can find one no problem. Could be a store clerk, doesn't matter. He'll be your wingman and can help you steer a lady into a date.
I would not advise finding your future beloved at a trashy place like a bar, as such fast women will leave your heart shattered and your bank account in no better shape. It is better to go to a library, a restaurant (doesn't have to be ritzy, but please don't choose a McDonalds), or even a net cafe (there you are likely to find more nerdy types who may share similar interests). If you see a lady seated alone (for goodness' sake have some standards; don't choose a landwhale, a trollop, or a non-white) walk over casually and with the utmost politeness and respect ask if you may sit with her. If she declines, whether because she's waiting for a partner or not, simply say, "I understand. Have a nice day" and walk away. If she accepts, congratulations, that's part 1 done! I am guessing you are not a total autist so you probably know how to hold a proper conversation. This is much easier if you have a wingman because ladies often venture in the company of each other; you can thus obtain an impromptu "double-date."
Remember when conducting your courtship that sex is not the goal, merely an accessory at the end of a wonderful journey. That doesn't mean you'll lack urges: in fact, rather than be frustrated from loneliness you'll be rendered passionate in the throes of love. Discipline is essential and you must never act unduly towards the object of your desires. Direct, rather, your passion into creative outlets such as poetry, songs, stories, or art; if you cannot do any of these now is the time to practice. Your emotion will be consumed by these practices until the happy occasion of your engagement and marriage, upon which you can use your animal urges to further the white race.
