Put on weight since sex

So I’ve put on over a stone since I last had sex and now I feel too body conscious to be naked and intimate with someone again.

Last time I was intimate I was so confident in my body and thus confident with sex. But now my body confidence has plummeted and I feel like my confidence in the bedroom has gone down too.

Plus, I’m seeing a guy next week that I last saw (and slept with) when I was much slimmer last year.

I’m just worried about what he might think since my body looks so different compared to last time we were together. And also the fact that if I’m not as confident in the bedroom then I won’t be as good and exciting- I feel like I was *good* and energetic before but now I just worry I’d be thinking about my tummy folding and stuff rather than just enjoying it.

Thanks in advance xx

(I’m 19 btw)
