I think the impact is negative, since sexual release reduces the desire of a man for sex temporarily, and with that the man will make less 'moves' to actual women. It's bad from an evolutionary point of view because the loss of actual sexual opportunity means there is less chance the man will have offspring. It's definitely not what the genes intended for a man to go for the junk food, so to speak, rather than the real thing, and so will damage the chances of a man for passing his genes. Of course in today's world, people are allowed to reduce one's chances of passing off one's genes, and do things like getting fat, watch porn, use condoms, have abortions. It's not a crime for people to sabotage their chances of finding a mate / having children. Preventing children from doing those activities to ensure their 'bright futures' as good husbands and wives with children is and should be solely the parents' responsibilities at their discretion.
