This is honestly completely sexist and incorrect. A female teacher might seem like a better teacher to someone who is female, as it is not uncommon for female teachers to irrationally and have bias favor female students over male students. This is also quite situational, as any male teacher can be extremely more compatible with their students than an antisocial female teacher. You may view a woman as a gentle and Matriarchal figure, but any teacher can emotionally and mentally support you, no idea what you mean by physically. Does your teacher massage you or something? This question bring too many variables into consideration, including the personality of said teacher, the personality of her audience (the students), the learning environment, and the gender or experiences of the students. I would also like to point out that your wording in the title can be seen as not specific enough. Better is a very irrelevant term that could refer to many different categories.
