Hahahahahahahaha,butterfly! You are not serious! Shebi na "if u can be thinking about d million and one issues of the country then its ok". How on earth can one be masturbating and not thinking immoral or sexual thots??? Some pastors sha. And truth is that,when one masturbates,one portrays the sexual thots to one's ideal man/woman (the person of their dreams,their fantasies) You rarely see a married man who masturbates while thinking of his wife! E go be one hot chic somewhere wey him dey fantasize abt. Same for d woman.
Anyhoo, i dont think masturbation has any medical implications if its done moderately. Except d person masturbates too frequently at what point he will run d risk of releasing more sperm than he is producing which might lead to fertility issues. For women,hmmm,poking urself in d vagina by urself does not sha sound nice or even comfortable to me. But of course, all man (or woman) to his/her own
