Getting wet and foreplay

So, my boyfriend and I are new at sex. And I get wet but because I sometimes get wet inside because I’m tight (which every girl is!). He thinks he is hurting me when he try’s to stick his dick in. But I try to give him tips like I tell him if you finger me or go down on me I will get wetter and the hornyness that is inside me will cum out, as long as he works it a bit before he sticks his dick in. But whenever I try to give him pointers on what will help me feel good he gets defensive that he thinks he knows better:/ idk is it me or do you think I’m right that I should have some foreplay and telling my boyfriend that what I like will make me more wet will help is good?
