>>29067925It really depends, my man. If you are actually very bad at sex yourself and you are super insecure about it, and your gf consistently has 'different sex' with other guys than you, then yes, its a very bad sign, and cucking is probably going to destroy your relationship. But that being said, its that the end of the world if a woman gets a little extra excited when having sex with a new man, especially if its a very masculine big dicked man. Regardless of how much she loves you or how attracted she is to you, the sheer fact that she's going to get fucked by a new guy is going to trigger her instincts a little harder than they normally do during an average sex session with you. It's a completely natural reaction and you can't blame her for it. You should embrace and encourage her to have good sex when she's with another man, and don't make her feel guilty over it.
