Should I do it?

I am a 17 year old virgin and I am in a committed relationship for 3 months and I want to have sex with my boyfriend but I am dead scared of getting pregnant and I am currently not on birth control of any kind what do I do!? He has never pressed me for sex or anything of the sorts he's so sweet and I want to treat him and also I am curious about sex...do I take the risk? Or just not do it?
