Yeah I dunno what to tell you. I don't know if your motivations are in the right place to begin with at this point. Smoke because you want to realize the potential of cannabis and benefit from its many effects rather than because you don't wanna feel left out with your boyfriend or because you don't wish to drink.

Also, I dunno if anyone suggested this, but maybe you're not physically smoking correctly. Are you sure you're inhaling the smoke into your lungs? This is a problem amongst many new smokers. It took me three different smoking sessions to finally take proper hits and get high. Try different smoking methods? Blunt, joint, bong, bubbler. My suggestion is to get your boyfriend to roll you your own fat joint or blunt and then you can smoke it at your own pace. Take a hit.. relax.. take another couple hits. Maybe put it out and spark it up again in 10-15 minutes and take a few more hits. You'll also be able to determine how high you are more easily you know? Like you can reach a point where you're feeling the effects take another few hits and be pretty high and then take a few more and be as high as you want...

I also dunno if you've got your head into it yet. I mean you're not gonna ever get truly high if on the inside you're worrying about it being bad for you or socially unacceptable...
