Having for the first time should i shave pubic hair?

You said your bf does not like it. Dear sister i suggest you that do not ever commit such mistake of having with ur bf. It is wrong. Anything relationship before you marry is absolutely wrong, do not do it. Bible says, "For God so loved the world that He gave His only begotten Son that whoever believes in Him shall not perish but have everlasting life." (John 3:16)
