low libido

With my ex, I had a very high sex drive, not necessarily because of him but just in general.
For almost a year now I've been with my boyfriend and I am rarely horny, especially when I'm actually with him. I want sex, I get really wet, I just don't feel all "hot and bothered" like I used to. Also, during sex, fingering, oral I feel nothing.
Also, if I finger myself I feel crazy amounts of pleasure, to the point where I can't finish because the feeling is too strong.
Is this normal? I can't really see a doctor about it.
