I found guavas in the local Asian store and bought one out of curiosity. While I have had guava juice, I've never eaten the fruit before.   I bit into the fruit only to find my mouth full of hard seeds, which were somehow less convenient to spit out than, say, watermelon seeds.   Seeing that most of the fruit is taken up by the seed-interspersed portion, I don't want to throw it out and only eat the small seedless part between the center and the rind. But spitting everything out is tedious.   Assuming that I want to eat raw guava, is there any trick to getting rid of the seeds more easily?  
I just bought my first guavas and was initially perplexed by the seeds, which I did not want to swallow.  The way I found to get rid of them and still be able to eat most of the fruit is:   Cut the outer fruit off from the center seedy area in 4 to 6 slices. Some of the seeds will still be in those fruit slices, but they push out easily with a thumbnail. Then you are left with slices of guava with no seeds. I found this way, though messy, to make them fairly easy to eat with no seeds.
