hey guys!
lemme start out by introducing myself.
im Josh and im 21
me and my girlfriend decided to have sex for the 1st time (yes both virgins

)
and well i had some of questions:
1) will condom ensure safety against pregnancy?
2) is there a chance of contracting an STD (never had sex before!)
3) should i use Viagra considering ive never had sex (only masturbated once

) and i dont know how long i will last or will i be able to pleasure her since ive heard from 90% of frnds that pleasuring a woman takes a while
thanks a lot!
