Do i really want this ?

My (M28) Cuckold fantasies getting more more intense. I Currently Watch a lot of Cuckold porn, like 1 Hour a day. Most of the times i dont Even Cum since i try to restrain myself. I think my kink started when my exgf of 7 years fucked another guy and letting me know about it. I ended the relationship because i always thought im more an „Alpha Male“… Im 6.6 Tall, VERY hung and fit. Now after a year i got a new GF and i still often think about my ex cucking me since that gets me going off. Currently im sooo confused on what or who i am. My new GF is more devote. I like being masculin and dominant for her and i love it to make her Cum. We still have Sex 4 times a week and she orgasms 2-3 times per Session so its not like i couldnt satisfy her.

My question is, am i a Cuckold ? Or just love to See her being pleasured? Should i introduce my new GF about this kink since we share an very intimate relationship ? Or should i just stop watching porn and hope this kink cools off? Thanks in advance
