anyone else’s husband/boyfriend afraid to have sex because they may ‘poke’ the baby? Lol

He doesn’t mind touching me but he doesn’t really want to have sex and nothing has changed in our relationship, we have a good relationship and always have and he’s very loving and caring but he keep’s saying he doesn’t want to poke her head 🙄 I’ve explained to him multiple times that it’s impossible and nothing’s going to happen and she’s well protected in there but he doesn’t seem to want to have sex and I question if it’s because I’m getting bigger (I’m 26 weeks tomorrow) but he say’s it isn’t
