starting to find male form, body, penis attractive

Hey. Story goes I'm 27 (male) and always identified as straight. My sexual experiences have been straight. If I jack off I think about past times or straight porn I find it hot. However I've recently started to notice the male form more and think "his attractive, good looking" if I see a naked dude or bulge i will look and compare and be drawn to, but i dont think about sex with them or being intimate.What's cause me to look at this head on is a straight friend recently came out as bi and seeing another male for the first time. When I found that out I got jealousy pangs and made me realise maybe I was into my friend in some way (enjoy being around him, good convo etc. If we at the beach I can think his good looking good body but I've never thought about him sexually at all)I look at males and find the male form attractive. But also the female form. I like vag tho for sex. I enjoy dominating a girl. I've decided i think i would be ok with oral with a dude, but no intercourse(I don't like anal with a girl neither)Confused. any advice, thought, experience, should I maybe explore?
