Should I stop dating a guy if I dont feel attracted to him sexually?

I am 24 yr old woman dating 30 yr old guy. We are dating since 3 months and like each other a lot. We get along well and have a good chemistry. The only problem is I dont feel sexually attracted to him. We have just kissed till now and nothing more than that. He tries to make a move but I dont feel right. He is good looking and a nice guy but I dont get the feeling. He has mentioned that he is a sexual person and would like to be more physically intimate as we are not just friends hanging out. I dont want to feel pressured or keep him waiting and frustrated for a long time. Should I end this amicably or wait and see if I get some feelings for him in a physical way?
