Possibly, but not necessarily, A man must pray a great deal, listening with both heart and soul to k now what God wants him to do. If you feel some attraction at this point, just continue to pray, go to Mass, and live a Christian life. If you are living a Christian life, Jesus will let you know when the time comes.
Also, go talk with your parish priest or with the vocation director. Try to come to diocesan-sponsored retreats and discernment nights. The vocation director can help you determine if in fact God is calling you to the priesthood.
