first sex

Ashlea
I have a question. I'm 16. So everyone is always saying that once you have sex for the first time, it changes your whole mind and view on everything. Like I have a boyfriend, we've been together for 1 1/2 years. We really do love each other and we are really close. We are also best friends. I'm thinking of having sex with him. But I don't know if it really does change a person, I know that it does, BUT, my boyfriend and I have done many other things, oral and hands. So would slipping him in me be really that different mind changing than just all the rest of sex that isn't full intercourse. I just am afraid of losing him because he really is amazing. So what my question is: one who has had every sexual experience with their partner other than intercourse. Does their mind really change just by having the dick inside the vagina, then just having it rubbing on the outside? Please respond.
