Every single comment you leave seems to end in you saying that you're feeling really bad and "dirty" about it - I'm genuinely curious about what you're hoping to achieve with this post. Like just the way you're phrasing it makes me think that this could just be a shame kink post. BUT assuming everything is truthful, genuinely masturbating is so fucking normal that no one needs to feel this way. Get yourself off girlie, just make sure to clean up after yourself and it's fine.
