Boyfriend doesn't like kissing!!

I'm so frustrated with my boyfriend we've been dating 6 months and he only will peck me on the lips I'm big on kissing and its so annoying he says he doesn't like saliva but come on!! He also isn't big on foreplay which is a big deal for me as well. Other than this he is a good guy and talks about our future together. Recently I've gotten back in contact with my ex I feel very guilty even though we haven't done anything yet but we used to have AMAZING SEX!!! I'm only human and have needs to I don't want to cheat but it's hard and I've definitely thought about it since my current bf doesn't wanna change but my ex I don't really see a future with him just fun times and sex is what are relationship was based on.
