Given the go for sex... but feeling insecure

So I had my six week follow up today and was given the go for intercourse and working out. However i am super insecure about having sex because I feel like my muscle tone just isn't there. The speculum exam wasn t painful and usually it is.. I feel like my husband is going to not enjoy sex now and that makes me worry. I know kegels help and I try and do them but idk what else I can do. I have already seen a physio so that's been covered and I guess it's just about time. but I hear all these other women say how it was tighter after birth or whatever else. And I feel like my body didn't get the memo... I know I sound like a crazy person. I am just very overwhelmed with it all
