wal-mart, k-mart, target, probably most drug stores... you're probably new at this... for God's sake don't get her pregnant. (I am going to hell over here for giving this kid tips on better sex).
My wife and I did everything but have actual intercourse before the wedding night... in other words we waited. Dude, don't forget she can spank your monkey with that stuff and you can slide your winky between her tits. For the love of Pete don't get this chick pregnant. Get her to lie on her tummy and slide your member between her cheeks. Then maybe you can talk her into sticking it into that virgin anus of hers... (use the "I don't want to get you pregnant" line). See if she can get on the pill and you need to be using condoms. I may get flamed for all this fear fear fear stuff, but you're probably young and believe me, you DON'T want to have a little you running around right now. (It's just that I am almost 30 and STILL don't have kids and because I am still in school I don't know how we could fit a kid into our budget right now AND I'M 29!)
oops, he's from overseas... try looking online for "assholeglide".
