so basically I've been with my boyfriend for a while and he wants to have sex and I kinda do to. we've done a lot of stuff besides actually putting it in in me. if I just use a condom is there still a big chance I can get pregnant. I don't want to ask my mom if I can use bc because she'd kill me if she finds out what I been doing. she'll probably tell me there's no reason for it and then question me about why I want to use it. I'm also 18
