Tell him you're offended by his sexual jokes and tell him to quit pressuring you. Say its not that you won't have sex with him, just say you're not ready. Sounds like the normal red blooded male to me.
it comes to medical schools? I am an aspiring doctor (pediatric surgeon) who will be starting off at a community college. Am I at a disadvantage compared to students who went to college/university right after high school? Do medical schools even take this into consideration? Thanks much.
