My partner likes anal sex very much, she has had plenty of experience and we practice it regularly. But, despite extended warm up sessions, a lot of lube and communication, she cannot accommodate my penis every time. I am always very gentle and caring. I know that even with the same partner each day is unique and different even if the mood and environment is the same. The situation is even more frustrating for me (and probably for her too) as we have often to stop after the tip of my cock has gotten inside her. It’s almost like some sort of reflex in her body just “rejects” me. What is the best way to achieve full anal sphincter relaxation, allowing an easy and guaranteed penis insertion?

There are no guarantees in life, especially with matters of the heart and ass. It sounds to me like your partner’s body still isn’t relaxed enough which is why her ass is rejecting you. A surefire solution is to increase the amount of foreplay. I suggest more warm up with fingers and toys, plus you should add clitoral stimulation to the mix. Using a vibrator, your hand, or hers to manually stimulate her clit while you play with her ass can increase her arousal and help her rectum expand for penetration.
Once you first get inside her, don’t make any sudden moves. Stay put and give her a chance to adjust to the feeling before you start moving in and out. When she feels relaxed, then start with gentle thrusting, and let her call the shots in terms of speed and depth. Take your time, listen to her body, and don’t put so much pressure on yourself and her to make it happen every time.
