I asked my GF her body count

My Gf (23F) and me (28M) were dating for 4 months now. Now it's getting serious we discussed matters to decide how should it go next. The other day I asked her about her body count before me (mine is 1 before her fyi) because it matters to me to decide to be involved in a serious relationship that potentially grows into marriage.

First she told me her body count is 3 and I confronted her that it was a lie because from the things she told me about her past I know she wasn't telling the truth. Then she said 5 was her body count. I still don't believe her , my guess is not less 8. I know she loves me but I really think body count matters and I believe about soul ties and everything.

Do you really think she is worth a serious relationship? And don't you think the fact that she lied first was a red flag?

TLDR, I think the girl I'm dating has many bofy counts and I got cold footed to make things serious with her.
