so confused about my sexuality, help?

[Star Girl]

im 16, and since a few years back ive always been sorta turned on by women. if i see a naked woman i get turned on, more turned on than if i see a naked man. i sometimes watch and masturbate to lesbian porn, but thats mostly only if i cant find straight porn where a guy goes down on th girl because i love my boyfriend going down on me. ive been with my boyfriend for a while and i love him so much! ive 'fancied' and liked boys for as long as i can remember, and i always seem to fall deeper for them than any other teenage girl does, and it takes me a long time to get over them. im just scared that ive been lying to myself and that i might like girls and not boys. before, it never even crossed my mind that i could like girls as well as boys, but recently i noticed that when lesbians get talked about i blush. ive never had any feelings for a female its always been boys and i always obsess over a fit guy if i pass one with my friends in the street. ive also been in the situation where ive thought some of my girl mates have been a bit too touchy feely and it always makes me feel uncomfortable, i havent liked it. im just feeling all this confusion because my boyfriend is on holiday and i ended up texting him telling him i watch lesbian porn because i feel bad about it and i cant get a reply until hes home. its sort of made me realise what ive actually been doing. am i just over thinking?
