Hi JemmaJune,
Have you discussed this with him? Maybe he does not believe in sex before marriage. Still, I feel after a year together, if you feel you are serious like you say, things should be a little more intimate. Cuddling, kissing, holding hands, physical bonding. You have your needs, and if he is not meeting them, it can make you feel rejected and frustrated, I can imagine. I would have a talk with him, to see if he envisions a future with you. Have you met his parents? If you make advanced toward him, what does he do..does he pull away? I would take all this into consideration and re-evaluate the relationship.
