Condoms, plan b and awkward conversations?!

OK SOO.. I’m not on any birth control and I’ve been seeing this new guy and having quite a lot of (really good) sex. HOWEVER, he never listens when I ask him to use condoms and always have to end up using the morning after pill. My body feels so out of whack now and the pill really isn’t making me feel good so I really need to convince him to use condoms!

Any suggestions on how? It would be really helpful
