My first gay relationship but I'm self concious !!!?

Truth is on the inside... and It would be nice to think that someone at 17 could already know that... and someone who's body is "perfect" at 17 has another 40 lbs to gain GUARANTEED by the time he's 30... so his body isn't always going to look like that.. unless he's a health freak and spends a LOT of time at the gym... which also becomes harder when you get into the world and have to "sing for your own supper"... and YOU'RE body can change as well... sometimes "hefty" kids slim out as they age... depending on your lifestyle... so the point is... ALL of what you're concerned about is temporary and superficial... what's NOT temporary is how you two relate to each other... how you show your love and respect... and who you are as a person... and if you don't realize that now... or he if he doesn't... you will definitely learn that lesson some day... I'm a lot older than you both and have a lot more experience behind me and I'm telling you... believe in yourself now... and spare yourself the heartache of having to learn the hard way... there's only one you... and you can not be replaced... most likely it wont be your looks that sends him running... it would be your insecurity ....
