<human>: Could you distill the essence of the text into 1-3 sentences?

Hello there fellow Redditors! Lurker here posting her sad little rant. Apologies if it's a bit garbled, I'll try my best to explain things.
22F bisexual here with a tragic dating history. Longest relationship happened when i was 15/16 yrs old for only 8 months, only others lasted for 2/3 months at most. I've been thru sexual trauma way back when I was 17, so I feel like my only real, not messed-up relationship was my first boyfriend. After a long while I've finally sorted my head out. So I feel like I can finally give myself to someone properly, without having too many fucked up issues. 
I have a few fetishes, and ideally I'd share these interests with a partner, but its no dealbreaker. I find myself being told I'm too "pushy", forward or intimidating to guys, and I've only had one girlfriend, but that did end on decent terms, unlike every other relationship thats ended badly. 
I am slightly overweight, and not that confident, low self-esteem and body issues, and my mental health is, eh, an issue that I'm working on.

Anyway. What I'd like more than anything in the world is a long term partner. I'm going into my final year of Uni and I've never had a proper adult, long-term relationship, and I want someone to share my life with, to be with. I'd settle for a sex friend or open relationship cause I've never had regular sex with anyone. I've not slept with the same person more than twice. So my dating/hookup history is yeah, tragic.
<bot>: I was messed up for a long time and feel like I'm ready for the long relationship that I've never had. What do you suggest?!
