hiii dear
i admire you for positive outlook
dear
masturbation and sex has lots of differences
though both are same at some point
but
premature ejaculation is defined only after you have sex
because it is also measure in the term of satisfaction from both the partners that are involve in sex
so my advise to you to wait up to getting married
and after you have such problem than seek for treatment
you can learn by while and by experience
certain other measures are there but it can apply only in sex not in masturbation
like
premature ejaculation can be treated with both psychologically and drug therapy
psychological means
to learn how to stay long
certain methods like women on top position
stop and start method of sex is very good results
read more on google
masturbating before sex can increase your time
proper play and understanding is needed
drugs like
dapoxetine will help you to stay long
so get knowledge from everywhere
hope for the best
take care
