Time is limited, I think it's possible for even a former pornstar to form a committed healthy relationship, but the odds are overwhelmingly against it. Given that, I'd say I think that it's not about the number as much as it is the type of person they are and each sexual partner carries some degree of any number of risks. People can want to change with all their soul, maintain it for a while, and then fall into old habits again. Then you may be out a couple of years and have had quite a painful experience or a 18+ year nightmare where you are reminded everyday of their infidelity or abuse as you see part of their face in your child. In my mind its not worth it but life can be rather messy and can put your hearts desire on the wrong side of steep odds.
I'd say equally important, it's a judgement of their ability to make decisions essentially, because all sexual experiences carry at least some risk, so quality of previous commited relationships matters. One night stands are like doing drugs or any other risky behaviour, a serious warning sign, but again life is messy, you have to deal with some issues with any partner.
Is women finding a man with a high body count attractive real or just something random dating coach types say?
It depends, are you attractive? In all seriousness a high or low number can be a turn off, most people would find it off-putting or strange to find out you've fucked half your home town or haven't even held hands with another person by a certain age.
