Considering you have tried already I wouldn't bother anymore at the moment. I assume you are in your twenties tops considering you are on Leakedbb (not to disrespect the older members).
Considering you are in your late teens early twenties, you are as a man in your prime sexual era (again considering you are a man). for women, this era is between 42 & 55. so I would advise you to try it later if you have the patience
considering you have above-average stamina in your 40 & 50s haha.
