Lasting long may not mean your girl is faithful in this generation.
Women dont really know what they want let me say most women even if you last an hour + a women that will cheat will definitely cheat, women are the cause why most men takes sex enhancement drugs just to satisfy them yet they are not satisfied this thing is common among men.
Further more sex is meant to be enjoyed by both parties taking sex enhancement drugs is not very bad but most men abuse it by taking it all the time just for there women to call them odogwu in the bed and most men collapse through this act just to satisfy your partner and yet they are never ok.
