hello!

So I met this guy and we really like each other. We have been spending a lot of time with each other. Tonight we went to the beach, had sodas, and watch shooting stars. He kissed me, but I only allow cheek kisses, which is fine. But the problem is...he is so attractive, physically fit and just wonderful. He and I both have great personalities and we make each other laugh and we always have something to talk about. We really hit it off. Trouble is that I am pretty overweight...I still have womanly curves but I am chubby. But he still wants to hang out with me and call me beautiful. I feel fat with him though. I can't believe such a great looking guy likes me. But also, he keeps wanting to do things with me like go swimming or cliff diving/jumping. Physical activities. I can't do those things that well. He loves doing daring activities. I'm embarrassed to be in a bathing suit near him. Should I feel bad? I told him I am sort of scared of an under current and so I am nervous about being in water. It was a small lie but I really don't want him to see me in a bathing suit or doing other physical activities. Please don't say,"oh just loose weight...." because I know this and I am trying, but it's kind of hard when this is all happening this week. I would really appreciate helpful advice. Thanks friends <3
