I've always had difficulty with eye-contact, and its worse with males.
I've always had difficulty "getting close" to people, and its worse with males.
Maybe its due to distrusting males more .. males are very literal, so you have to try very hard to not have them "mis-interpret" (judge) who you are .. females are more emotional, and see things more as they really are .. and [so] are more accepting of the true you.
But males are also easier to "get along with", due to saying exactly what they think, and not "reading between the lines" as much. That is, as a general rule:
Males SEE & SAY more literal, Females SEE & SAY more emotional
. . . . bad . good . . . . . . . . . . . . . . good . bad
Also, since i've never had a partner, maybe i'm "scared" of males, as i might not know who exactly I am sexuality-wise (scared that they might "rock the boat", in whatever way)
