It's very irresponsible to blame others for your lack of sex. If you want to pursue girls, then do so and don't expect others to know which side of the field you're playing on, especially when you state you're bisexual. There are plenty of bisexuals who predominantly favor one gender over the other, and it sounds like you favor females over males. Being bisexual can be very confusing for others to understand, so it is YOUR responsibility to make yourself very clear about what it is that you want out of love and sex.
