It does happen with most of the men who ejaculate semen in good quantity as there is no enough space to keep the semen there so naturally it would spread all over. However, make sure that you wear it properly and you have selected a suitable size for your penis. It would not affect anything as it is still a protection so do not worry about pregnancy when you have sex with your woman so this way semen would not reach deep inside the vagina.
