Should I be trusting this?

I have been with my boyfriend for 2 1/2 years, engaged for 11 months. For the past 1 1/2 years, my fiance has been progressively declining in affection. I am the one that had to initiate sex, cuddling and hand holding 95% of the time. He doesn't kiss me passionitly. When I do initiate sex he sometimes turns me down.I am the one that has to progress the act or he would just continue to kiss forever. He has complained that about the lack of sex because I get tired of always having to initiate it so I stop trying. He spends at least an hour in the bathroom in the am and right before bed on his phone. He vary rarely goes to the bathroom without it. I have tried to talk to him about it all but nothing ever changes. I need some advice.

Lack of sex has been known to destroy relationships. You need to make it clear that this is very important to you and you will not continue this way for ever. Some times people have a more subtle approach to initiating. Its not a "wanna take your clothes of" comment, It may be just a more "come hither" look. You may need to tell him you need more aggression during sex. And FYI in my own experience this sort of thing doesn't get better so good luck. I have tried all sorts of things from telling my bf that we needed to take turns initiating to buying sex outfits, to talk after talk after talk until I just loose my desire to even do it with him......3 years and counting.

Hello, he needs to tell you why he's not initiating sex with you & why you're the one who's initiating it 95% of the time. It seems like you love sex & he doesn't. This isn't good at all like a previous comment said lack of sex has been known to destroy relationships. Let me ask you something, what if he tells you he doesn't want sex a lot? What then? Do you love him or would you go elsewhere to find sex? I'm just curious.
