For some women, sexual compatibility is everything: They will not commit to someone who doesn't completely satisfy them in bed. Other women treat sex as only one piece of relationship and are willing to compromise on sexual excitement for the sake of the man's other qualities or their shared values. So, I wouldn't say you're doomed, but if you don't find a way to spice things up, you will always be sexually frustrated. If he's boring to you now, what do you think he'll be like in 20 years?
