If he was convicted of criminal offence (eg, indecent exposure if it could be proved the spa rumours were true), then England would not select him.
But apart from criminal convictions, I don't think your employer should decide whether to employ or promote you based on your private life. If everyone is a consenting adult, then it's not relevant to your employer if you choose to have sex with one, two, three or multiple people at the same time.
If you show up for work on time and do a good job, then anything else is not your employer's business.
England are selecting him to play football, not to be a role model. They also don't decide if he promoted products etc - those are commercial decisions made by other companies choosong to employ him. If they think he tarnishes their perfume/vitamin/clothes brand, they won't employ him.
If someone sees him as a role model, that is on them. Not everyone in the public eye has a moral obligation to behave in a certain way, be married, faithful, demure etc, just because of the risk someone might admire them.
He is a terrible man. But I wouldn't want my employer to make decisions about me based on my private life, so it would be hypocritical to expect the same for him
