You can definitely correct this behaviour. May I ask how you lead your pony? Does she/he stay at your shoulder? Do they move with you? Do they push into you or remain a respectful distance from you?
Because it sounds like she/he does not have respect for your personal space. You need to teach her to lead correctly, focus on you and respect your space.
Clinton Anderson has a nice video on this (one of many, you can search YouTube for them):
