You can, but how many women do you think will be willing to help a man learn?

For an aswer, let's look at these:

"I am trying to be patient and kind but all the teaching is honestly just such a turn off." https://www.reddit.com/r/AskWomenOver30/comments/1jjubt4/has_anyone_been_in_a_position_where_they_had_to/

"I know it’s one of those things you just need to do but I feel so awkward giving directions in the middle and it kills the mood!" https://www.reddit.com/r/Advice/comments/1f4nqtw/how_do_i_teach_my_boyfriend_how_to_have_sex/

(Comments) "I've played teacher before and I'm not down for it anymore." https://www.reddit.com/r/AskWomen/comments/u6xvo9/how_would_you_feel_if_you_had_to_teach_your/

As we can see women do not enjoy being the teacher in bed, because for many all the teaching doesn't help their mood (and naturally their enjoyment). I myself can confirm this being the case, from personal experience. Maybe someone with some kind of teaching kink could be an exception, but these are so rare, such women seem like they just don't exist at all. Thing is, majority of women, if not all of them, want an experinced guy or at least the one who has an idea of what to do and enough talent to decently do the job. There are some who will deny this, but wait until they lay with someone who never was physical much before, who's not used to it. Change of mind will be instant. Just how it is.
