I think it can be. when I was single, I'd get horny and wank, then the thought of it would make me hard again. it was kind of setting the wheels in motion and it wouldn't stop....a viscious circle
having sex got that same way, after the wife and I got married, and we had our own place. the sex was very, very good. I thoroughly enjoyed pleasuring my beautiful wife. my refractory time was almost nil, again the thought of it just made me hard. wfe said just the thought of my big cock, made her wet. I don't know how many times she called me at work to meet her at home for lunch. sometimes on the weekend we would fuck 20 times or more starting Friday evening. I can remember leaving the groceries in the cart in the store on Saturday morning, and going home and fucking. and I had just fucked her before going to the store. since I had given her first orgasm ever, she often said, "what did you do to me?' "I think about it all the time." And we stayed like that, sure it slowed during her period, but we couldn't wait for it to be over. We even missed a dinner date or two with our closest friends, another couple our age. we were very close and at one point we disclosed how much we fucked and they were shocked. they thought they fucked a lot, we were about twice as much. anyway, we had sex like that for 4 years, started a family. things kind of cooled off after that, but after our 2nd child. we were back to fucking 2-3 times a day., more on the weekend.
