A general question regarding cutting ?

Not sure if this is the correct place for this question but I thought I would get more feedback regarding my question. I am currently into week 5 of my bulking diet and taking Deca and Teste E. Now I know I will gain some fat with the amout of calories I am consuming. Is their any point in cutting after this bulking cycle as it will be well into the summer by time I am finished or would I be able to continue bulking right through the winter and then start to cut up for next summer. I read in a book that you bulk then cut then bulk and so on. Is this correct ?
