What do you guys think?

Should we force our daughters for not being in relationship when they are teen, encourage them or keep quiet until they got older? and how does the religion deals with the each situation?

Yuwie

Has any one tried Yuwie? and does it really work?

Masturbation ?

Excessive masturbation is bad for health? True or false? if ture how it might affect health, i.e which parts of the body are highly affected? Post your answers.

Regards,

je ?

Does any one know whether we can make the following JE or not?

Cr. Expense xx

Thanks,
