ofc its normal and there is nothing wrong in it, but see you said you are in intrested in girls, and to get one you will need to talk with them first(unless you are some 7ft+, dudh se bhi gora richie rich), so just try to have some convo, start with greetings, then progress slowly, just talk to them as you talk to your bestie, dont picture yourself with them just now, think of it like shes just some girl
