Is Everyday Masturbation Healthy? and Am I a Lesbian?

i started masturbating when I was 14 years old. back then i use three fingers to rub my clit just to feel an orgasm. then when i get used to it, two fingers would satisfy me, then down to 1 finger to rub my clit. when i went to college(16/17 yrs old), it was like every week. i've also tried to insert two fingers on my vagina but mostly, i only rub my clit and minora.  when i turn 18, its like two to three times a week, then it came down to once a day. are there any health risk in everyday masturbation? I may be pathetic to be satisfied through masturbating alone. i had a boyfriend but we only went far as to kissing(smack, oh how pathetic). sex is not much in our country, or i should say on the environment i grew up in. i wanted to try having sex too, but im afraid(a lot of teenagers that time are getting unwanted pregnancy) thats why i never asked on my previous boyfriend. i have a classmate in high school who wanted to have sex with me, he became my long distance boyfriend(my university was two towns away) for only 2 weeks because i ended up refusing him when he asked me to have sex when i go home =P, i really really really am afraid. when we saw each other again last last Christmas(he arranged a party with high school friends), i got drunk. he carried me to the bathroom to puke >.< i was sitting beside the potty when he gave me a glass of water. after i gargled he kissed me.. thats my first passionate kiss. then he put his hand under my shirt and under my bra and massaged it. im a bit embarassed because i have small breast. then he lay the futon. we lied in the futon for two or three minutes(both speechless staring at the ceiling) then he turn towards me and started kissing me again. he gently massaged my breast then started to poke my nipples. then he slowly inserted his hand on my pants, he was about to finger me when our friends enter the room. it was very wrong timing. then after that, we never spoke about it. were just friends now. i think i was a bit disappointed that we never ended up doing it. i dont want that to happen again, being left hanging, so i decided not to have boyfriends nor entertain suitors for the time being. im satisfied enough to do myself. but lately i think im being more turned on watching girls do each other. im also imagining myself doing it with my cute friend (girl). am i lesbian?
