As a qualified 1, skilled foreplay is essential. The best method is to fully engage in licking the entire body (note that licking lightly is useless), focusing on areas such as the lips, ears, neck, armpits, nipples, belly button, upper thighs and the diagonal line connecting the abdomen, penis, scrotum, perineum, and anus. Start with the front and then move to the back. I highly recommend this position - have 0 get on all fours, spread their legs and lift their buttocks, while 1 uses their tongue to continuously play with 0's anus. Reach under 0's crotch with your hand and pull back, continuously stimulating 0's penis. In general, even those who are not willing to be 0 cannot resist (as long as the rectum is clean, feel free to lick, the louder the licking and sucking sounds, the better).
Once the external part of 0's anus becomes more relaxed, you can try inserting a finger, but be careful not to go too deep, just one joint of the finger is enough. Try thrusting a bit to let them gradually adjust. When they have adjusted enough, you can apply lubricant and insert your entire index finger, followed by two fingers (for those who have not been penetrated before, don't be too loose, otherwise it won't be any different from having sex with someone who has had sexual experience. As for those who have been penetrated before, play as you wish, the looser the better). Your task as a 1 is to try to find 0's prostate. The prostate is like a ball of meat, usually located about 5 to 6 centimeters inside the anus. Once you find it, remember its location.
An excellent 1 also needs to have good psychological resilience. Being 0 is actually very painful, no matter how many times, it will definitely be uncomfortable when first penetrated, not to mention the first time. So 1 must take it slow. You can try going in a little bit and then completely pulling out, wait for half a minute, then insert again, gradually going in a bit more each time, until finally fully inserting in one go. Those who have experienced it know that the most difficult part to penetrate is about 2-3 centimeters inside the anus, but once you break through, you can go all the way. Of course, it's not as complicated for the first time.
During the first anal sex, no matter how skilled 1 is, 0 will definitely feel uncomfortable when first penetrated. After 1 opens 0's anus, 1 can lie down and let 0 sit down on their own. Generally, this position allows the intestines to form a vertical line, making it very convenient for the penis to enter and minimizing 0's discomfort. It is also a psychological suggestion for 0 to overcome their mental barriers and remember the feeling for a lifetime. The same thing is completely different when done actively or passively.
When 0's anus has been stretched enough through self-play, it's time for 1 to take the initiative. For some 0s, no matter how many times or how painful it is, they will get an erection as soon as they are penetrated. For others, they may only get an erection after their anus has been stretched and penetrated smoothly for a long time, so it's normal for them to not get an erection at the beginning or in the first few times of intercourse. 1 should remember to try different positions, be firm yet gentle when first penetrating, and push towards the direction of the prostate. One very important point is that 1's penis and 0's prostate should form a 45-60° angle, continuously rubbing against 0's prostate to create pleasure. 90° will cause pain, so avoid it at all costs. Also, at the beginning, it's not necessarily more pleasurable to penetrate deeper, so don't go all out right away, as 0 may not appreciate it. After trying each position, 1 should ask for 0's feedback until finding the position that makes them unable to resist pleasure, and then stick with it and continue thrusting. When 0 is feeling extremely pleasurable, encourage them to vocalize it and try to control the muscles between their scrotum and anus by tightening and relaxing them. Finally, 1's task is to last and keep thrusting, from the moment 0 experiences intense desire until being ejaculated inside, which usually takes around 10-30 minutes.
When 0 is ejaculated inside for the first time, their whole body will naturally convulse (similar to when a woman reaches orgasm and her whole body twitches). 0's anus will tightly contract around 1's penis, and after ejaculation, the muscles will reflexively push 1's penis out. Don't rush to pull out, comfort 0 appropriately, and continue thrusting. After being ejaculated inside, for a few minutes, 0's anus will feel like it did when it was first penetrated, so enjoy it. After about 5 minutes of resistance, 0 will start to feel pleasure again, and their anus will become even more relaxed than before, entering a state of numb enjoyment. At that point, 0 will be unable to resist the physiological and psychological pleasure of being penetrated, so 1 can confidently and freely thrust without worrying about anything else. After about 10-15 minutes, it's very likely that 0 will urinate after being ejaculated inside. There are two possibilities for this: the first is that it will spray out like semen, but it will be urine, and the anus will still tighten; the second is that it will come out like urine, and in this case, 0's anus will completely relax.
As an excellent 1, after ejaculating inside 0 for the second time, you can do as you please - try different positions, depths, intensities, frequencies, whatever you want, and ejaculate whenever you feel like it.
