anyone find it hard to cum during sex ?

[Yamser]

Ok i can cum in a few mins if i have a wank . But finding it hard to cum when having sex and maybe once in my life i came from a bj . But if i get a handjob i can cum . Like i normally get tired after about 20 mins of riding (i need to get fitter lol) but still lately during sex im finding it very hard to cum

Btw nothing to do with the woman . There very very sexy and so friendly and never rush me

so this happen to anyone else ?
