No, not necessarily. It's all about expectations. Keep them at bay.
Some examples:
If you wife up an obese woman and expect her to hit the gym with you or enjoy long walks somewhere.... disaster.
If you marry a ratchet bytch and expect her to have good credit... disaster.
If you marry an alcoholic and expect a sober relationship and/or that bottle of Hennessy to still be there when you get back from the bathroom... disaster.
If you marry Bill Cosby and expect not to ingest a quaalude or two... disaster.
If you wife your sister and expect for your child not to come out deformed... disaster.
If you marry a dog and expect it to speak English... disaster.
Otherwise, ain't nothin' preventing these from being fruitful eternally lasting relationships and all that jazz.
So, if you wife a slut and expect her to practice sexual exclusivity... disaster.
Realistically, you should expect to share that girl in multiple capacities and if you're okay with that, then have fun you idiot. Cuckolds and hotwives do exist and have successful marriages. Just let a brother get a turn at it though.
*That's not to say those things won't happen but you shouldn't expect them. That's also not to say that changes can't come but you shouldn't expect a person to be what they're not. You should love them for who they are and what they can become. You never know, you might be the only guy she allows to put it in her ass or you might be the only one she lets bust on her forehead or something. Have fun.
