Am i a little bit of a cuckold ??, No, most certainly not, i can go far longer than most and unlike a lot of punters, have the mindset to satisfy the lady 1st, me 2nd....
Actually, you are indeed a cuckold:
cuckold/ˈkʌk(ə)ld/
a man whose wife is sexually unfaithful, often regarded as an object of derision.
"jokes in literature about elderly cuckolds and misers are rife"
verb
verb: cuckold; 3rd person present: cuckolds; past tense: cuckolded; past participle: cuckolded; gerund or present participle: cuckolding
(of a man) make (another man) a cuckold by having a sexual relationship with his wife.
"in the novel Humberto cuckolds his employer"
(of a man's wife) make (her husband) a cuckold by being sexually unfaithful.
"he was repeatedly cuckolded by his wife Aphrodite"
Also, be aware, many punters very much enjoy bringing pleasure to a WG, they get off on it and it's part of the fun for them. They pay for that fun, sure.
Whilst I wouldn't presume to say your missus enjoys sex with you less than with punters (I'll assume you're in a loving and trusting, longstanding relationship), be assured that every so often there will be a guy who is younger than you, sexier than you, better body than you, bigger cock than you, smelling better than you, and even, freshly showered. Whether she gets off on that, only she knows, and like most savvy women, she'd be mindful of not hurting your feelings by telling you how good he was.
It may be of course, that part of your relationship is having her tell you about all the guys she fucked, it may be a turn-on, and that's fine
