Masturbation a sin

Queen E

Hi everyone. Am in a distance relationship. I got to see my husband once a year. I really do love him and am so committed to our marriage in every aspect. But because we are far apart from each other I usually gets so honey and frustrated. A girl friend introduced me to masturbation and the use of sex tolls. I tried using it, watching videos on YouTube that talks about masturbation and sex. And I come across a video of a pastor saying it is a sin to masturbate. That it’s attracts evil spirit to yourself. That’s why some people dream of having sex Which is bad. And it also affects our physical lifestyle like broken relationships and financial instability. So my question is, has anyone heard or have any idea or education on masturbation as a sin. Or experiencing any setbacks in life for doing that???? Please my English may not be perfect but just try to get the sense out of it thanks 🙏🙏🙏🥰🥰🥰
