for the first time?

so my bf and i were planning this for like weeks.. im a virgin and he's also a virgin.. ofcourse we are planning to use a condom bec. we wanna make sure that we are safe.. i will not get pregnant right? or have some STD? bec. others said they were like bleeding nonstop and they were infected.. i was thinking that if i have condoms we are free from that? especially me?
