I know I'm not a guy, but I don't like it when a boyfriend calls me all the time, and demands my attention constantly. I'm a fairly independent person and it tends to piss me off after a while, it makes me feel like he's codependent. I've even stopped having feelings for a guy over it. (He called me multiple times everyday and insisted that we spend time together constantly.).
If a guy calls me more then twice in a day, and we don't have plans, and there's nothing wrong with him or me, then he's calling me too much. If he wants to talk we can make plans and meet somewhere to socialize. I think that phones bring a level of detachment to the table that is inappropriate for getting to know someone. I just don't like telephones, and guys don't seem to understand that.
