Would you get seriously involved with a guy/girl if he/she......

[cheerfulgreek]

Here's the situation. Lets say you found a guy/girl very attractive who was really nice to you, never disrespectful, but during conversation you asked he/she how many serious relationships he/she were in. He/she told you, and then you asked how many people was he/she was intimate with. Let's say he/she told you a really high number, and at the same time he/she said they don't sleep around like that anymore, would you continue dating them to try to get serious with them, or would you just end it?

Also your thoughts on if it would be that important to even ask the question.
