the best and no side effect way to u and ur gal is use condom...
pill = chemical = birng side effect , no matter how the scientis mention no side effect bla bla bla...it might due to our current technology cannot detect the side effect now. but god know after 3-5-8 years only found out that is side effect...it already harm ur gf...then how??
or u already break with her, then u ruin her life!
Think twice before u did it...Gals please think if ur bf ask u do it...
Ask him back, y don u use condon...n it is easy to clean the mess!

Dude, love u gf, care about her health...Use condon...else no sex!!
