Shaving my pubes (vag) ?? i need help!?

i've been shaving for a few months down there, trying to please no one but myself. when i shaved, i always went agaisnt the grain with just plain water in the shower and i would get like bumps and a few pimples yuck! BAD WAY TO SHAVE I KNOW. im a virgin so it cant be std's. i just researched shaving and i was wondering if i would still get these bumps if i shave WITH the grain and with my dads shaving cream ? lol. advice ?
