1st off...congrats for poppin ya cherry!

most kids are made through "crap/shitty/quicky" sex! If you plan it then unlikley she wont come pregnant, its usally wen its quick and crap lol

I have 3 kids, im only 26.....most times i have made her preg. is wen we have a quickie or something like that....just watch her periods, if they late like a week or so then do a test!

Best of luck mate!

Peace
