Losing my virginity

I'm almost 15, and I know it sounds sort of sketchy but I'm getting more interested in loosing my virginity. I've been in a relationship for over 2 months now. Him and I have been going a little quick but he's not interested in having sex until we hit at lease a year. Me on the other hand, I feel like I'm up for it. Anyways, either way I am extremely afraid of becoming pregnant or doing something wrong. If anyone has any advice, or tips that would be great. Maybe brands of condoms? Or positions that could make this time great? Or something I could preform to increase the spark. I've already given him oral, and he's previously had anal with another girl a couple years back. He's older than me keep in mind. I think it would be more awkward of an expirence for me but I could be wrong.
