Hello. Tell or say please, what normal pause should be between the first and the second sexual certificates or acts in day at 21 go years or summer men at employment or occupation by sex in a condom if regular enough sexual life (almost every day) is conducted. Whether can arise at such rhythm absence of an ejaculation at the second certificate or act which has come or stepped approximately in 15 minutes after the first? Thanks.

Dear Dmitry! So short time intervals are usually insufficient for restoration of excitability of the centers of an ejaculation. Therefore the second sexual certificate or act at many men will last more longly sometimes rather longly (while this excitability will not be restored)
