So i just want to ask girls about something and i would try my best to describe it in words so I am an 19 year old boy and i have never been friends with girls and and have very minimal interaction with them so i really don't know how to talk to them or behave with them and today I am not asking about that I am asking that sometimes it happens we boys see (I don't know about everyone but applies to me) some girls that looks good or rather cute and i really don't see them with lust or something it's just there are some natural beauties that we like and admire them but it happens sometimes for example that I was traveling on a train and the girl on my front seat was really beautiful and cute i really didn't see her with lust I just liked her cuteness and i don't know why but my eyes just got stuck to her I tried to distract my self but couldn't help it but i felt that I am making that girl insecure or I was looking like a creep I just want to know how can we boys make you girls feel safe and secure i was on that train for around 6-7 hours but i didn't talked to her but I still wants to say sorry to her if I made her feel insecure i really had a lot of eye contacts with her that made me feel like that and i really want to stop myself from getting attracted by cuteness because I really love a girl she's my only female friend and I have a huge crush on her and i even know she doesn't have feelings for me maybe because in looks wise I maybe and 4/10 guy but she is always kind and helpful to me

In short I just feel guilty whenever I get attracted to cute girls and I just want to know how I can make a stranger girl feel safe and secure around me that she doesn't feel I am a creep or something if I have to travel or something with anyone

And sorry if my post is too long because i really can't express my problem in words properly
