Being in a relationship doesnt mean that you never get aroused by anything else ever again. It just means that you dont act on it. I think its healthy to maintain the ability to be aroused in other situations. Relationships shouldnt be a prison.Youd have gotten hard before, and you should now. As long as you know that the only person youre going to be sliding your big hard cock in to, were fine. There really is a happy medium between the craziness of your parents with their compulsion to continue having sex with anyone they wanted, and couples who expect one another to be perfect at all times with the idea that no feelings of sexuality outside of the relationship are acceptable. Both of those types of relationships would never work for me. Whats perfect for me is that we stay ourselves, and make each other truly happy
