Greetings ...My Husband Is Well Stocked Below And When We

Greetings ...My husband is well stocked below and when we have sex it's always been soreness afterwards but this wk we had sex and it sent sharp pains through my stomach and whole lower area ...he said he felt a section during sex that seems new and i felt ah direction change as well . Do i need to c the doctor ? I took some pain pills and it eased up. Am I too small or shallow?
