Hi, Thanks for posting in HCM. Injaculation (retrograde ejaculation) is a term used to refer to releasing semen inside your body through your bladder instead of outside your penis (ejaculation). Generally people injaculate for the following reasons: To cure ejaculation hangover, to help combat loneliness, to lessen libido, as an anti-depressant, to prolong the time it takes for orgasm, as a form of birth control, there’s less of a mess and to help monogamy. Generally, there are no negative effects, but that doesn t mean it’s safe. Ejaculating semen either outside or inside is normal physiological phenomenon and does not have any ill effects on health. Since it is a physical act, it may cause physical exhaustion, but it is known to relieve mental stress and helps to generate new and active sperms by getting rid of old ones. Hope the information provided would be helpful. All the best.
